Three more experience counter commanders have been printed in Kelsien, the Plague, Minthara, Merciless Soul, and Otharri, Suns Glory, making a silly experience counter theme deck possible
Anytime you attack you get to exile the top card of your deck until you hit a nonland card, putting three time counters on it and suspending it outside the game
The activation cost is unaffected if it already costs one or zero mana (such as the activation cost of Zirda's last ability)
So what are the differences between these decks and simple control decks, practically speaking
Their goal is to summon Prediction Princess Tarotei, a high-level ritual monster who can flip monsters face up or face down during either players turn
Is it reasonable to print at that level of efficiency?
