BOGLES

COMBO DECKS

Most of combo decks in this format are about Saheeli Cat. But we saw one particular one that made 5-0: The combo consists of playing Jeskai Ascendancy on 3. And on 4 playing Sylvan Awakening, which will turn your lands into creatures. From now on you only have to cast spells to untap your lands to generate more mana while gaining +1/+1. The combo is fast, interesting and has consistency, the problem that needs the enchantment that cost 3 in play and spells that aren't instants, so it loses to Abrupt Decay.
