Tricky Terrain Tricky Terrain has got it where it counts, in the mana base
On the topic of reusable creatures, Anger thrives from being in the graveyard and Skarrgan Firebird can make for a large headache (as can his newer comrade, Magma Phoenix)
It's all centered around loading up your permanents with charge counters, which breathed new life into a lot of classic cards from back in the early days of Commander
Vedalken Orrery and Leyline of Anticipation As you can see from #18 Rout, simply taking a card that would have hit #36 on the list (Damnation) and give it flash for 3 more mana gives you have a card that rises massively in value
If you plan to upgrade this deck, theres quite a bit of +1/+1 counter and X cost synergy available in Temur colors
Another thing that I like about Wilt is that you can always use a card like Regrowth to get it back later if you cycled it early on and then wound up needing a removal spell
