Well, with opponent hax it should be easy
Pet vodoo doll
Qtower
6x seed
Turn 1: play tower, triple infect doll. 3

Opponent: Qtower, Qtower, 6x chaos seed (all infect) YARG KILL DOLL. 9

Turn 2: 3x seeds are TU, 27

+9

original = 36

on him.
If you want exactly 30 then your first TU is instead another infect.
Without opponent hax I need more thinking...
