Derevi, Empyrial Tactician Derevi, Empyrial Tactician has one of the most absurd abilities in the game, ignoring commander tax by entering from the command zone for 4 mana every time at instant speed
It also has a much more affordable mana cost and the morph helps with tricking opponents into killing something else first
Dragonkin Berserker Having a 2/2 first strike in play is very good in the early game, and if you dont need Dragonkin Berserker anymore, you can cash it in for a much better 5/5 dragon
If an opponent wants to kill with targeted removal, theyll lose 7 life on the spot
For example, Kaheera, the Orphanguard's restriction is that all creatures in the deck must be either a Cat, Elemental, Nightmare, Dinosaur, or Beast card
