You receive fewer boosters which may seem less value, but the Set boosters offer a higher ceiling on what you can open
This card is the reason why the format is balanced: as I said before, combo decks like Creativity and Belcher play various disruption spells (for one mana Veil of Summer, for zero mana Pact of Negation and Teferi, Time Raveler) so Force of Negation is the best answer to back up another counter, due to its unfair cost
Not all of these will be meta-defining, but all of them have their place, and with enough future support, are sure to make it onto plenty of deck lists
Targeting one of your creatures with a spell lets you make a copy of that spell that targets Ivy while shes on the battlefield
For that cost, you gain control of X Creatures and Planeswalkers
