How it works
Activate Phyrexian Altar by sacrificing Woodfall Primus, adding B/G.
When Woodfall Primus dies, its persist ability triggers, returning it to the battlefield from your graveyard with a -1/-1 counter on it.
Whe Woodfall Primus enters the battlefield, it triggers, targeting any noncreature permanent.
Holding priority, activate Quillspike by paying B/G and removing the -1/-1 counter from Woodfall Primus, giving Quillspike +3/+3 until end of turn.
Repeat.
You may also repeat this loop as desired during future turns to destroy any number of noncreature permanents.
