Dihada's first ability gives a legendary creature you control a plethora of keywords until your next turn, making them the perfect defender against your opponent's incoming attacks
This is the only card that allows you to commit crimes, in this case by targeting one of your opponents creatures to no effect, for zero resources, arbitrarily, at instant speed, as many times as you want
You also want to prioritize getting Evasive characters on the board since this deck has more than any other Starter deck
Also note that this is part of the Commander deck led by Y'shtola, Night's Blessed, which specifically cares about casting noncreature spells with mana value 3 or greater
As an example, Im going to use my Dimir Rogues deck which contains only three single copies of a card
Yuffie Kisaragi (Yuriko, the Tigers Shadow) Yuriko, the Tiger's Shadow often serves as an entry point for players looking to get into cEDH, but its quite powerful at all power levels since commander ninjutsu cheats the commander tax
