In a Two-Headed Giant game, the Beast token can attack or block with a creature controlled by your teammate, even if no other creatures you control are attacking or blocking
Just note that, if you choose to use these infinite combos in the Commander format, you may run out of cards in your deck before all of your opponents are dead
And remember, you have two of these slots, so youll have double the chances to open the card you want (or half the packs, depending on which set of data you like to work with) and this is the formulation they used in Bloomburrow
Unless you have an effect that doubles counters on permanents you control, like Doubling Season
Darksteel Mutation Exxaxl: This might seem like a weird pick to some, but completely strip your best creature of anything it can do can be an incredibly impactful play on an opponent's board state
glorious :) Aside from that, wonder what your take on Archmage Ascension and As Foretold would be in a deck like this
