You never want to reborn the frog rigth? It revives with 0 frogs and slows the scaling. Also, having the cabra buffs your mininons, causing your beasts not to die, which is basically what you need on frog comp. I guess it does not matter now that leaps were removed from the pool lol.
It doesn’t really matter, once you reached critical mass. Ideally, for best case you want 3 golden birds, reborned, the first possibly taunted, the gold forg taunted and 3 gold rivandares.
