mtg proliferate deck commander Magic: The Gathering Edge of Eternities - Toxic proliferate deck commander options

Cards are added to the official app a few days to a few weeks after release.

For the former, you can use Coastal Piracy to have tokens available for defence after each unblocked attack, any card drawn can be combined with Mystic Redaction, Sphinxs Tutelage or Psychic Corrosion, the Mystical Tutor and Solve the Equation help us find the right cards for any strategy, for example Time Warp, Pyromancers Goggles or Swarm Intelligence (matching the Commander)

Also, a note on Power level

Tinybones Deathtouch makes this 1/1 much more likely to deal damage to opponents, as sacrificing a Creature to block such a small amount of damage never feels good

Cards or permanents they've chosen previously during this process can't be chosen again

But it might be news to you that you can deal near-infinite damage with Devil with a few other cards in play
