This is key, as Grolnok allows you to cast spells and play lands from exile with croak counters on them, meaning that through attacking, Grolnok's ability can effectively draw you three additional cards each turn

Table talking can allow this card to blow up eight problematic creatures, which is rather unheard of for just four mana

When you do, untap all other creatures you control

This is pretty great and an excellent outlet to spend your excess mana
