What's the minimum number of creatures that should be run in order for Domri and Garruk to be effective? I'm currently running 27 in my list, but I'm finding that I'll often miss on Domri and only pick up one or two cards on Garruk. I'm also running one mainboard Mizzium Mortars and a Clan Defiance, on the theory that aggro matchups are common enough that the added utility makes up for decreased planeswalker efficiency. Thoughts?
The list is very tight. Ideally in most Colossal Gruul, 23 lands, 8-10 planeswalkers, 27-29 creatures with 9-12 fatties, or so called win condition. Nowadays, people are trying to use lesser mana dorks and more win condition since Garruk most of the time end up drawing dorks instead of what we're hoping, fatties.
You need to run the following:
23 Land
16 accelerators (creatures)
10 planeswalkers
11 fatties (creatures)
So you could theoretically get more than 27 creatures by shaving a land or a planeswalker off.
