Bronn, Avaricious Sellsword

Trample
Alexios, Deimos of Kosmos attacks each
combat if able, can't be sacrificed, and can't attack
its owner.
At the beginning of each player's upkeep, that player
gains control of Alexios, untaps it, and puts a +1/+1 counter on it. It gains haste until end of turn.

"Till I get what I'm owed, a dragon doesn't get to
kill you. You don't get to kill you. Only I get to
kill you..."—Bronn
