Use two Irritators and two Indom Rex G2’s and you can set up the last turn (only two turns in Round 1 and one turn in Round 2) so that a Closked Indom Rex G2 with two MF’s, 2 GT’s, and 2 RtC’s on it hits Sino and massacres him. We got up to 16,320 damage with a unboosted, level 15 Indom G2.
Irrit 1 DSS, RtC, GT
Irrit 2 DSS, RtC, GT
Indom G2 1 Cloak, FR, MF
Indom G2 2 MF, Cloak, FR
If you have boosts on your Indom G2 for the second round hit, im guessing you could get damage over 18,000???
