My advice if you are building a Kaseto deck:
Make Kaseto your primary attacker. Build a deck that pumps him & use his own ability on himself. Find ways to keep him safe from harm such as giving him hexproof & use cards like Giant Growth & other pump cards to bring him up to a 21/21 & just swing for lethal unblockable commander damage.
