Here’s a very nice Jeskai Ascendancy decklist from a man that many people believe comes from the future or at the very least has very good ‘Future Sight’ Yuuya Watanabe.
3 Battlefield Forge
3 Shivan Reef
3 Flooded Strand
2 Temple of Epiphany
4 Temple of Triumph
4 Mystic Monastery
2 Valorous Stance
1 Glare of Heresy
3 Disdainful Stroke
3 Anger of the Gods
2 Outpost Siege
2 Sarkhan, the Dragonspeaker
It’s indeed a very cool deck with some spice. He’s running the full playset of Soulfire Grandmaster as well as some Citadel Siege (about time we see this card in Standard decks). Another note of interest is that he is forgoing Lightning Strikes in favor of Wild Slash. I’ve seen quite a few Jeskai builds without all 4 Goblin Rabblemasters, but I’m guessing since you always want something attacking your opponent on turn 4 with the help of Citadel Siege, you need to increase the odds of it happening.
I guess he ate something spicy, hence the firebreathing
I’m used to playing the Jeskai deck with 4 Seeker of the Way so that it can confidently attack past would-be roadblocks like Sylvan Caryatids. While you do gain life by attacking into them with Soulfire Grandmasters, we’re not really advancing our game plan versus decks like GW Mastery of the Unseen or most midrange Green decks. You’re mostly glad to have them against speedier decks, where those little chunks of life being gained matter more. Also, having guaranteed lifelink is much better when you’re boosting your creature each turn via Citadel Siege.
I really adore the Sarkhan, the Dragonspeaker out of the sideboard. He too, works well with Citadel Siege and can do wonders with a couple of +1/+1 counters (like taking out an Elspeth, Sun’s Champion). He’s also that extra piece of removal for those pesky Whisperwood Elementals. Another cool card out of the sideboard is Outpost Siege. While the Khans option will be used more often than not, it is worth nothing that it effectively functions like a burn spell when you cast it in Dragons mode quite often (since your little tokens tend to die).
I tested the deck a few days ago and it under-performed, however there was this really long game where all I drew were about 12 lands (Scryed 3 at the bottom and fetched twice) as well as 3 x Soulfire Grandmasters.That’s it! no other spells … You kinda have to shrug that one off at that point. I went back to a more conventional build for today’s local Standard tournament and it fared only slightly better. It’s almost as though I could have swapped versions and done much, much better.
