mtg landfall deck commander Yarok the Desecrated Double Triggers / EDH 100 card Custom Commander Deck*** Tatyova, Benthic

That isnt all, as youre also able to remove two counters (note, they dont have to be +1/+1 counters) to exile the top card of your library, and you may play that card this turn

Exiling something for 4 at instant speed is just always going to be good

One non-dragon commander that may like the Hellkite is Child of Alara, a WUBRG deck that may wipe the entire board to start things over, then reanimate threats like Two-Headed Hellkite to resume the offensive thanks to haste

Our commander is also a flying lifelink so if Arna is the one swinging for that damage not only do we have evasion but we gain enough life that any opponent left alive will have a tough time killing us before our next turn
