pokemon mewtwo ex card (62/162) [XY: BREAKthrough] [1] Energy Absorption Attach an Energy card from your discard pile to this Pokemon Team Rocket's Mewtwo ex (231/182)

Y'shtola, Night's Blessed I find it hard to consider Y'shtola, Night's Blessed outside of the context of Commander because its abilities are so neatly balanced and passively useful, even the stats of 2/4 vigilance underline this excellent card

Honorable Mention #2 (#12 Overall) - Takara Just like Squee, Takara starts with 10 cards rather than 7 and has that as a max handsize

Chaos: Whenever you roll Chaos, destroy up to X target artifacts, where X is the number of creatures you control

Sage of Shaila's Claim: [Category 1] ETB yield is 3 Energy for 2 mana, then you can spend the Energy any way you want

I wouldnt be surprised if this was in more EDH decks than Sol Ring
