War of the Spark

Bond of Insight | Sorcery | | Each player mills four cards. Return up to two instant and/or sorcery cards from your graveyard to your hand. Exile Bond of Insight. | Joe Slucher

Jace's Triumph | Sorcery | | Draw two cards. If you control a Jace planeswalker, draw three cards instead. | Kieran Yanner

Invade the City | Sorcery | | Amass X, where X is the number of instant and sorcery cards in your graveyard. (Put X +1/+1 counters on an Army you control. If you don't control one, create a 0/0 black Zombie Army creature token first.) | Sung Choi

Neoform | Sorcery | | As an additional cost to cast this spell, sacrifice a creature. Search your library for a creature card with mana value equal to 1 plus the sacrificed creature's mana value, put that card onto the battlefield with an additional +1/+1 counter on it, then shuffle. | Bram Sels
