It has a very fast, very narrow gameplan: if you can get your Charizard ex in play, you will have the energy to attack with it, and it will hit like a truck, so you best make that happen as fast as you can
Its passive adds a +1/+1 counter each time you draw your second card a turn, and it ultimately lets you swing in for a win
Cards like Inspector let you play more one drops without lowering the power of your deck
Pick key pieces, value engines, or just that annoying character you cant work around, and as long as you dont exert Bellwether, theres little they can do about it
If a creature has in its mana cost, X is 0 for the purpose of determining its mana value
In this set, Items seem to be getting the biggest buff, with a few new ramping capabilities
