They wont work together,,,
both are pure offensive clans which have only tiwi as defense in deck..
u maynot be able to activate frozn bonus when needed..
for frozn to work at best u can mix with roots, night etc...or even with some poison like cyb or dolly cr,,
I think Piranas and Frozn can work, just that it's more challenging to pull off...
I'm picturing Frozn power and damage scare tactics alongside Pirana's pill manipulation mind games. Opponent won't know whether to underpill or overpill against a charging Dalhia.
