Xenan Gauntlet Grinder

I used the original list (4 Annihilate, 2 Rat King, and 2 Farmer) to reach 12 streak win complete runs, which records 84-0. Then in a middle of a run I encountered power screw. Stuck at 2 powers for some turns and later 3 powers without SS, and loose to some small hybrid creatures (which cannot be killed by Annihilate and Send an Agent).

Now I think Farmer and Rat King are good in shadow heavy decks, but not in a time heavy Xenan deck. You sometimes don't have SS at turn 2 and turn 3, and this inconsistency is bad in gauntlet decks. So, I made a small change (4 Annihilate => 4 Banish, 2 Rat King+2 Farmer => 4 Exploit) and works very well so far.
