Creature — Merfolk Wizard
The Lost Caverns of Ixalan Commander
72/100
Gains value in 2HG: hits each opponent.
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
Flying
Other Merfolk you control get +1/+0 and have flying.
