Decks have 60 cards, including the commander and their Signature Spell, an instant or sorcery that sits outside the deck with the commander and can only be cast when its commander is on the battlefield
Both his - abilities are somewhat situational and so he is one of the few planeswalkers that doesn't in some way become a threat if he sticks around too long
Theres a political approach to this card and it can tutor up an entire combo or multiple finishers all at once, so Im not ruling it out completely
