In the right Commander deck, I suppose it's not impossible to play four spells in a turn
Plus, you probably wont put this commander in the command zone since it returns to your hand from the graveyard if its killed
If you want something a bit more catch-all for any deck, however, try Duplicant and Meteor Golem
Our options are therefore as follows: Azorius v Jund: Will, Scion of Peace & Ikra Shidiqi, the Usurper + Kediss, Emberclaw Familiar Rakdos v Bant: Judith, Carnage Connoisseur & Shanna, Purifying Blade Selesnya v Grixis: Trelasarra, Moon Dancer & Solkanar the Swamp King Boros v Sultai: Firesong and Sunspeaker & Zimone and Dina Golgari v Jeskai: Beledros Witherbloom & The Archimandrite Okay, there should be six, but if you can find an oppositional pair in Dimir and Naya that can both be reasonably called a life gain deck, go for it
Since then, golden Pokemon cards designated as hyper-rare have been released
As long as an opponent has eight or more cards in their graveyard, Thieves' Guild Enforcer gets +2/+1 and has deathtouch
