Jeskai Ascendancy is one of the strongest cards printed in recent years. The ability to go off in infinite combos helped lead to the bannings of Dig Through Time and Treasure Cruise in Modern. Filtering through your deck while pumping your team and fueling your delve spells is an incredible combination of effects.
I played Ascendancy in Standard at Pro Tour Dragons of Tarkir last year and really enjoyed the deck. The format continued to get more hostile toward the strategy, especially with Dromoka’s Command becoming a staple; and the loss of a spell as powerful as Stoke the Flames, which allowed you to deal a large amount of damage, filter a card, and untap your team that you used to cast it, was devastating.
Token decks continue to do well in Standard, and using Ascendancy as a complement to it is apparently still a viable strategy. Dragon Fodder, Hordeling Outburst, Secure the Wastes, and Gideon, Ally of Zendikar are great ways to go wide on the board. Gideon can also be used as an anthem effect to go along with Jeskai Ascendancy.
Jace, Vryn’s Prodigy as the only spell in the deck that doesn’t trigger Ascendancy makes sense, as you’re loading up on spells that you want to flashback and can fill your graveyard quickly. This is the type of deck where Treasure Cruise can really be abused.
The optimal build may include Magmatic Insight, as no deck that can use Insight better than this one.
