Deck is made of 2 drops. I have ran a similar set-up to this in FRF, and was able to get away with only having 2 land on the field most of the time.

As long as I have a turn 1 drop, and a turn 2 drop with potential for future growth in my hand I won't mulligan.

Raider's Spoils is an unfortunate must have in this deck as I need a plan in case my board stalls out, and I've already dropped my hand. The +1 attack for all creatures in nice, and Aven Skirmisher is in the deck to hopefully sneak through and draw me cards.
