If your hand matches a card on top of a stack, it must be moved to that stack
I have no doubt that with Force of Negation to slow down early decks by countering Aether Vial, Faithless Looting, Ancient Stirrings, and the like, Modern will be a more hospitable environment for decks with eight or more cards that cost four or more mana

Leinore helps guarantee you almost always hit your coven trigger by putting a +1/+1 counter on any creature you control, then, if you control three or more creatures with different powers, you draw a card
This will allow players to build their collection via Constructed play more quickly and reliably than they previously could
And dont forget about the companion mobile app, which maximizes gameplay and tracking of cards
