While at first glance this looks like your average four mana clone, pretty interchangeable with any number of blue cards for EDH players who want this effect, it's actually a fair bit better than most
It does not, for example, change when you may activate abilities that can be activated "only as a sorcery." The last ability cares only about the amount of mana that was actually spent to cast the spell, regardless of its mana cost
She would be rated higher if it were not for the high number of other good fives drops and othe good "Nissa" cards
It compliments cost reducers super well and makes your force overwhelming in a burst or two of spells
Thats why Im sitting here, staring at Itos card art like a crevice in a cardboard Amigara Fault
For example, Path of Exile 2 has built a strong following around its intricate economy, where players rely on trading and managing valuable in-game currency
