I have 2 ash and 2 droll because i don't like having hand traps x3 that can be used once per turn.
I play 1 invocation because the first game i need 1 invocation only, i would add second invocation for the 2nd and 3rd game but because i main crossout designator really i don't need second invocation.
I main lightning storm because for me the most important turn is my first turn ,doesn't matter if i go second or first, even if i draw lightning storm other turn i can just use it as material for mechaba
Some players would consider adding Small World but i don't use it, i think 18 starters for creating a board is enough and i don't need more than that.
