Soulburner's deck, the Salamangreat archetype, is a perfect example of this phenomenon
Celes' hand-sculpting ability interacts well with flicker effects, allowing you to consistently rework your hand
The set is smaller than average (similar to Aftermath), consisting of only 110 cards (including basic lands)
You could ask: Are you going to attack me this turn? Do you have a counterspell in your hand? Are you able to win the game this turn? If I were to ask you if you concede the game, would your answer to that question be the same as the answer to this question? Spark Fiend is hilarious because its not entirely clear what the card does, why it does it, or how it does it
If you control a Nissa planeswalker, instead search your library for up to three land cards
Its 1st effect lets you special summon 1 Level 4 or lower BEAST variant monster from your hand or GY during your opponent's Main Phase
