Hunter Sliver Yes, this little sliver needs some help to force some really bad blocks from your opponents, but when Hunter Sliver and a few friends get online, provoke is a rare ability that ensures there is no escape for opposing creatures
Purphoros, God of the Forge, as you can imagine, goes in Impact Tremors style decks, usually in builds that spew Goblins
The pre-made deck here is all built around strong glimmers that are able to challenge (Mulan's "Reckless" ability forces her to do this each turn if she's able) and gather Lore quickly
(Look at the top X cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) Once Lydia Frye has been blocked, increasing the blocking creature's power to 3 or greater won't cause Lydia Frye to become unblocked
Refute Refute is a solid upgrade on Cancel with a loot
