I've decided to do this top ten because there has been too many top ten best cards, so don't be surprise to see no holy awe. So here goes.

10. Critical Blade: Even though this card might be a little situational, the chance that someone will run at least a few blockers are quite high. For a small cost of 2 mana, you can get rid of Gran Gure, or even Ladia Bale!! Is also a shield trigger, which makes it even more useful.

9. Ghost touch:  People often underestimate this card because it is a one for one trade. The usefulness of this card is that after the first few turns, they will most likely has cards in their hand that they are saving up for.  It is not that hard to use either and when you have a hand advantage, you want to keep it that way. It also brings your opponent a step closer to top decking.  Just try it out in a black deck and you'll see what I mean.

8. Ultracide Worm: 11000, double breaker with NO summoning sickness? enough said.

7. Corile:  Most people think that this card is too costly, but that is not true.  This card can really annoy your opponent and can give you a huge advantage because the monster is not bounced back to their hand, but the top of their deck, which sets them back one turn.  Using corile on an evolution monster just hurts.  This card can really help you control the flow of the game.

6. Larba Geer the Immaculate:  This card is very underrated in my opinion. For five mana, you get a 5000 monster that can tap all blockers. To me, that's practically a Holy Awe right there since you get to attack their shields with no blockers to stand up to your attack.  Evolving from a guardian makes it a cheap and useful investment when you have no need for La Ura Giga anymore. 

5. Poison Mushroom: I heard a lot of people said how bad this card is because it promotes a hand disadvantage. That may be true, but for a green deck, this card can help you get the edge you need like a third turn barkwhip, or a fourth turn dual fang.  As you can see, this card can help you get one turn ahead of your opponent, or even two with bronze arm tribe.

4. Rothus the Traveller: This is an amazing card, four mana to kill any creature is just ridiculous. I know you can't choose the creature to destroy and you need to destroy one of you own, but that is just a small drawback.  Most people don't use Rothus as a monster anyways but more of a spell, plus he helps you get rid of monsters that you wouldn't need after its current usage, like bronze arm tribe to trade for one of their own.  Many top players around the world uses Rothus when they use red, is easy to see why.

3. Bronze Arm Tribe:  Another amazing card that can set you a turn ahead of your opponent in mana wise without the hand disadvantage. The measely attack is nothing to worry about since he can be evolve into barkwhip or dual fang.

2. Chaos Worm:  This cards owns so badly because it kills any of your opponents monster that you choose.  I've used this card long enough and it saves my butt all the time and put me in a great field advantage.  I mostly just summon him to kill the big monster he has on the field, then attack the smaller one.  Is like killing two birds with one stone. It fits perfectly into a black deck since you have so much cards to destroy their monsters and their hand.

1.Natural Snare: People might say terror pit is better, but in my opinion they are a tie, but since this top ten is for the most underrated, this card deserves number one.  When you're in your midgame you wouldn't be needing mana that much so giving them an extra mana is no big deal, especially to kill off any of their monsters. ALso five mana cost is cheaper than terror pit.
