Just remember that Overabundance can do the same to you when building your deck having some nonland options to generate mana or a couple free spells to take out enchantments can go along way toward keeping you from accidentally locking yourself out of the game
Whenever you think about making a new deck decision, you have to respect these ten cards and what they do to the rest of the format
Liliana of the Veil We, of course, have to end off on the most incredible card in this set: Liliana of the Veil
If this card attacks an opponent's monster, during the Damage Step only, negate the effects of that monster while it is face-up on the field (but its effects can still be activated), also its ATK becomes half its original ATK
As long as Altaria ex is on your Bench, you can heal 20 damage to each of Your Pokmon every single turn making it a good card to consider for any deck
As evidenced here by Armageddon
