Obvious combo is obvious

[Anitar]

Dual Cast Twinflame to get 3 hits per sword. Combine with Seize the Day and one of your Firecats can take two attacks with these astronomical odds.

If you have height or any other attack bonuses - or even if you don't! - your opponent can kiss their Planeswalker goodbye.

Ouch! Dual Casting on Twinflame. Killer combo. However, you would not also be able to use Seize the Day, because that would be 4 spells on one turn; Twinflame (1), Dual Casting (2), Twinflame again (3), stop. So Dual Casting can only ever be played as the second sorcery spell card during a turn.

Activate Jace, Investigator. Summon Lantern Gheists, look at other player's top card with Eerie Observation. If it's a good sorcery card, leave it on top of that library and use Jace's Search for Answers to play it on your opponent. Boom!

Bump, because I figured out an obvious combo that didn’t need its own thread. With Chandra, hit an enemy squad with Burn From Within, and then use Malevolent Whispers to force one of them to move. Free hit for all members of the squad, plus the obvious free turn.
