Hello Pojo Fans,
Crystron Sulfador is one of those Level 5’s you’ll be playing to set up your Graveyard.
A double Foolish Burial for Crystron when Normal or Special Summoned, Sulfador can Special Summon itself by popping a Crystron card on the field, virtually eliminating the need to tribute for its summon. While you still can, it wouldn’t destroy the Crystron, so why would you do that? Sulfador also offers some versatility by being able to use this effect in the Graveyard.
Popping a Crystron card will activate the destruction effect of any of the Crystron Synchro Monsters that were Synchro Summoned on the field. It’s hard to think of you popping any of your larger Crystron Synchro Monsters to Special Summon this card to get that double Foolish Burial, but all of them will give you back a monster or a Crystron Monster upon destruction. The double Foolish Burial can send Prasiortle to banish to Special Summon a Crystron in your hand, Rosenix will give you a Crystron Token when banished, Smiger may be the best though, as it adds a Crystron Spell/Trap from Deck to hand when banished. Smiger can search Cluster or Inclusion which are two of the newest Spell/Trap cards for the archetype and do a lot for the strategy.
Inclusion is a Continuous Spell that will RoTA for your Crystron, while also providing battle protection for a Crystron monster the first time it’d be destroyed. Cluster provides banish protection from opponent card effects (extremely important for the Crystron and need to be banished to activate other effects) and is also Continuous as a Trap Card. You can also run Crystolic Potential, though that Field Spell offers no protection or negation, no search off activation, but can get you draws each turn equal to the number of Crystron Synchro Summons you made that turn, so it could end up being a +2 or 3 depending on your situation. Sulfador has some good targets for Spell/Trap as well as its typical Crystron monster choices.
Tristaros can Special Summon him off an opponent’s card effect, Synchro Summon using him, and now Sulfador is set up in the grave to bring itself back and get you a double Foolish Burial. Those monsters it sends to the grave will undoubtedly be banished to Special Summon more Crystron or add something to your hand.
Sulfador may be a dead draw unless you have a Crystron card on the field, but you have plenty of Main Deck cards to supply it with a destruction target. Once you get that, you’re getting your double Foolish Burial and that is going to set you up more. A great turn for Crystron involves getting this effect to go through so you can use your grave and set up a board for next turn.

We got another new Level 5 non-Tuner for the Crystron archetype that assists in making your plays up today, Crystron Sulfador.
Sulfador is a Level 5 WATER Machine with 1900 ATK and 2250 DEF. Odd stats for a Level 5, plus it’s WATER Machine like all other Crystrons. If this card is in your hand or graveyard, you can target a Crystron card you control and destroy it to Special Summon this card, but you can only summon Machines from the Extra Deck for the rest of the turn. Combined with Crystron Inclusion, which searches for this, you should have a way to start your combos since upon Normal or Special Summon, this sends 2 Crystrons with different names from your Deck to the graveyard, putting cards like Smiger or Thystvern to search for more Crystron cards, Tristaros for his graveyard effect, or some of the archetype’s Traps for their graveyard effects or to recover off their new Synchro. You also got Crystron Sulfenir for another Level 5 to revive itself to either get to Cyber Dragon Infinity, or Sulfenir destroys himself to summon a Crystron Tuner from the Deck. HOPT on each effect of Sulfador is expected. It’s for sure a useful card to start or extend Crystron plays. You got Inclusion to search for this or Tristaros can just summon this from the Deck for Crystron names in your graveyard. Another very useful card for Crystron.
Advanced Rating: 4/5
Art: 4/5 Wonder if this has a connection to some of the Duel Terminal lore and the -lswarms with that 2250 DEF.

Crystron Sulfefnir was already one of the deck’s best cards, so obviously it had to get an even stronger form with Crystron Sulfador, a level 5 WATER Machine monster, just like the original Sulfefnir. 99% of the time this is the card you want to grab with Crystron Inclusion, a card we won’t be covering this week but it’s hard to discuss Sulfador without mentioning it! Notably, as a level 5 Machine, you can use it as an Xyz material for Cyber Dragon Nova, and it’ll be a good non-Tuner for Crystron Quariongandrax as well since the deck’s best Tuners happen to be level 2. Sulfador’s stats might seem a little random, with 1900 attack and 2250 defense (very mediocre, by the way), but they’re actually the averages of Sulfefnir and True King Bahrastos, the Fathomer. Lore!
Sulfador has 2 hard once per turn effects; the first can be used if it’s in your hand or your Graveyard, letting you target and destroy 1 of your own Crystron cards to Special Summon itself, locking you into Special Summoning Machine monsters from the Extra Deck for the rest of the turn (is there a single Crystron card that doesn’t lock you like this?). Might as well get the second effect out of the way, because it directly leads into it; upon being Normal or Special Summoned, Sulfador will let you send any 2 Crystron cards with different names to the Graveyard. What you’ll send varies on the combo line, but in my experience the safest options are Crystron Tristaros and Crystron Cluster. Like I said before, you’ll almost always be searching and summoning Sulfador using Crystron Inclusion, which conveniently has a Graveyard effect that’ll let you revive Triastaros and go into their new Synchro monster, which will also recycle Cluster in the process for more disruption. I can’t stress enough how much this card relies on Inclusion, to the point you’ll want to max out on Crystron Smiger and use Clockwork Knight just to get to Inclusion. It’s well-worth it, considering it’s your bread and butter combo; we’ll get more into the new Synchro monster later. There’s plenty of other targets you can use with Sulfador, including Sulfefnir and Crystron Rosenix, but I think Tristaros and Cluster are the main cards you’ll want to send. Even without Inclusion, Sulfador can enable some decent 2-card combos, though Inclusion lines are still very appreciated. The only real thing to complain about with Sulfador is the fact that it’s a level 5 brick and will often be stuck in your hand unless you have another Crystron handy, so most lists opt for 2 copies to avoid that risk; you’ll need 2 anyway for Cyber Dragon Infinity combo lines.
+Excellent combo piece that accesses other key cards
+Enables Rank 5 plays with Crystron Sulfefnir or another copy of itself
-Heavily reliant on Crystron Inclusion for its full potential
-Needs a Crystron on field to summon itself
Advanced: 4/5
Art: 4/5 I liked Sulfefnir’s lime green colors more, but I dig the new pose!
