Heroic Challengers have never been a great deck.  Doubt they will be.  It's probably a good card for them because it essentially a searcher that gives you another LV4 to XYZ with.  The revive from graveyard effect requires it to be in the graveyard first, requires you to take damage (which you don't want to be doing often) and summons it in Attack Position so you're risking taking even more damage.  I don't see it as splashable but it does give the theme some more XYZ fodder.

Hello Pojo Fans,
 
HC Thousand Blades is the Summoner Monk for the archetype. Very searchable by several means (Giant Rat, RoTA, another copy of Thousand Blades, M-X-Saber Invoker, etc). 1-for-1 once per turn if in attack position is an even trade to set up an Xyz Summon of a Heroric monster. The restriction of only Heroric monsters prevents any abuse of mass Special Summoning (the addition of Summoner Monk with this monster gives you the potential of 3 Level 4 monsters).
 
A free Special Summon of this monster when you take damage of any kind (even by your own cards) can set up the repeating process of when this monster is in attack position. Once per turn for either of these effects is balanced, but the fact that HC Thousand Blades isn't banished after using its Special Summon effect benefits the player tremendously. Special Summon HC Thousand Blades after taking the final damage for the turn, draw, then ditch a “Heroric” card to Special Summon another “Heroric” monster (any level, another plus for flexibility). With enough cards you could run through the Thousand Blades in your deck in one turn and set up 2 Xyz Summons.
 
A solid card for the archetype.

Review for 9/8/2015

Once again, I believe the effects on this monster are switched. Heroic Challenger - Thousand Blades is a Level 4 Earth Warrior-Type monster with 1300 Atk and 1100 Def. This is definitely weak on all fronts. However, part of the reason we are reviewing this card is it's utility as a Level 4 monster. Rank 4 monsters open up while this is card is in the Graveyard.

The first effect is only usable in an Heroic Challenger. Once per turn, while this monster is in Atk position, you can discard an "Heroic" card to Special Summon an "Heroic" monster from your deck in Def position. However, you can only Special Summon "Heroic" monsters for the rest of the turn. The second effect is where this card shines. While this card is in your Graveyard, you can Special Summon it in Atk position after you take damage from anything once per turn. The combo to consider is with Performage Trick Clown. Trick Clown can Special Summon any Performage monster from the Graveyard when it is sent there from anywhere. Then, you take 1000 damage which would trigger Thousand Blades. All of a sudden, you have two Level 4 monsters on the field during either players turn. This is part of the reason why Lavaval Chain was banned. Satellarknights and other Level 4 Warrior decks might love this card for it's combo with Ring of Destruction or other self damage effects.

Score: 3.5/5 This is easy to run at 1 for defense in any deck.

Art: 3.5/5 I didn't count, but that looks like a thousand blades.

I would really hate to have to be the person behind this guy in a line at the DMV.

Joking aside, we have a great support monster for the Heroic Challenger theme. While his ATK and DEF are weak, he's able to give you a chance to grab and summon a bigger and better “Heroic” monster from the deck. You'll have to discard a “Heroic” card to do it, but if there are any Spell.Trap cards with “Heroic” in its name, then you might not have to sacrifice a monster.

Also, if you're under attack while Porcupine here is in the Grave, you can special summon him in ATK mode and possibly save yourself from a game over.

Overall, not a bad card. Weak, yes, but useful. Melikes. 

Final Score: 4/5 (Heroic deck)
