Nesting Grounds

Destroy all lands.

1, T: Add BR.

Whenever you attack, you may sacrifice another creature. When you do, choose two — • Create two 1/1 red and white Soldier creature tokens with haste that are tapped and attacking. • You draw a card and you lose 1 life. • Caesar deals damage equal to the number of creature tokens you control to target opponent.

When Dogmeat enters, mill five cards, then return an Aura or Equipment card from your graveyard to your hand. Whenever a creature you control that's enchanted or equipped attacks, create a Junk token. (It's an artifact with "T, Sacrifice this token: Exile the top card of your library. You may play that card this turn. Activate only as a sorcery.")

Whenever you cast an artifact spell, you get E (an energy counter). T, Pay E: Target creature gets +1/+0 and gains trample and haste until end of turn. T, Pay EEE: Draw a card. T, Pay EEEEE: Return target artifact card from your graveyard to the battlefield tapped.

Flying Whenever The Wise Mothman enters or attacks, each player gets a rad counter. Whenever one or more nonland cards are milled, put a +1/+1 counter on each of up to X target creatures, where X is the number of nonland cards milled this way.

Vigilance, trample, haste Whenever Liberty Prime attacks or blocks, sacrifice it unless you pay EE (two energy counters). 2, T, Sacrifice an artifact: You get EE and draw a card.

When The Master enters, target player gets two rad counters. T: Put target creature card in a graveyard that was milled this turn onto the battlefield under your control. It's a green Mutant with base power and toughness 3/3. (It loses its other colors and creature types.)
