Counters everywhere! That's the plan. And Trample. That's good, too.
Corpsejack Menace doubles counters on everything. It gets ridiculous.
Karametra's Acolyte dumps mana based on your devotion that is amped up by Kalonian Tusker and Bow of Nylea , which is amazing in its own right
Mistcutter Hydra
feeds off the acolyte! giving it a ton of counters! and grows with you as the game progresses.
Reverent Hunter
does the same. Cast it early as a chump blocker and later as a win con.
Nylea, God of the Hunt and Bow of Nylea provide trample and deathtouch making everyone all around nasty.
Lotleth Troll and Scavenging Ooze feed off the dead and get bigger and bigger. Discard a card to the troll then for one, drop a +1/+1 counter on the ooze. Unless you have Corpsejack Menace out. Then drop 2 counters. Or 4. Or 8.
Savage Summoning is a cheap anti-counter, oh-I-actually-do-have-a-blocker-and-he's-bad-ass card that is amazing. Plus one (or two, or four) free counters?? Crazy!!
Witches' Eye
helps you move through the deck with scry. Perfect to cast on your hexproof Sylvan Caryatid. Don't need mana? Check the next card...
Those are my thoughts for the deck. This deck is a lot of fun to play. I would love to hear how you would improve it. Let me know!!
