On her own, shes already annoying, a two-turn Dig Through Time glued to a three-mana planeswalker
Thats an absurd amount of value for only two mana, and thats not including the fact that youve probably already got some value from it by casting it in the first place
The Despot gives the controlling player Monarch status, and at the start of each upkeep a 5/5 red Dragon creature with flying ability is put into play as long as you remain in possession of that status
It will mostly be used in G/R Ramp style decks alongside Hour of Promise as a somewhat inefficient removal spell that doubles as a finisher against control decks, but I could also see red aggro decks that play it in their sideboard for the control matchup because of one card: Settle the Wreckage
4 mana is a lot to pay for scry 1, then draw a card or play a land, but when you have nothing better to do with your mana, this card will pull you far ahead at a surprisingly quick pace
