I’m excited for Foundations, mostly for Llanowar Elves returning. But Day of Judgement, being a reliable 4-mana sweeper, is also going to be rough. Current sweepers in Standard include:

3 mana:

• Path of Peril (6 mana for full sweep)
• Brotherhood’s End
• Corpse Explosion
• Temporary Lockdown

4 Mana:

• Depopulate
• Ill-Timed Explosion
• No Witnesses

5 Mana:

• Deadly Cover-Up
• Gix’s Command
• Burn Down the House
• Unstable Glyphbridge
• Sunfall
