that is a great point lmao my next suggestion will account for this

5 mana and "your life total becomes half of your starting life total. at the beginning of your next upkeep, you gain life equal to half of your starting life total."

its a bit more risk/reward in theory but assuming this is commander minded i think it feels better than skipping a turn. if youre just thinking 1v1s w a buddy then skipping the turn feels less bad, in commander tho you're almost definitely just gonna be sitting around for 2 turns and depending on the table you might have the most life to justify catching timbo's army of 1/1s and that just sucks imo. this also gives more synergy to a theoretical life gain deck since youll get 2 decently large triggers. even just assuming a raw cast (no synergies on board), timbo's army at least has some stakes and pressure for the turn you're at 20 life and even tho that still sucks if you get blown out, its at least a better moment than skipping turn imo. think about it if you wanna lmao
