full power boujack really sucks; replace with a support. even without Zenkai, the distributed blu gogeta is better
also, you can get dbz broly grn for free; use 1000 gems on him to get a solid fighter.
turles when zenkaied is pretty good, but try to get super gogeta red which is F2p and gokua can kick some hybrid ass. overall, at high stars, can be viable in the 30-40 meta, and at low stars, in the 20-30 leauge.
