You get to pick two opponents if the game is coming close and could be won via burn, and it's harder to remove, at the cost of an extra mana
Now usually this wouldnt be too strong because the opponent might have stronger monsters than you except Toon monsters (with few exceptions) can attack the opponent directly
Or you can use multiple discard effects to spread the love around a fleet of creatures, kind of like Balmor, Battlemage Captain, except you get to draw cards
That's quite the combination of cards, even if you're talking about 9 mana and then some for the whole package without affecting the board in the meantime
Like the planeswalkers they find, these spells are overcosted and underwhelming
While showing off the set, Wizards of the Coast revealed that this set will bring about a major change to MTG
