So basicly, after collecting a vast amount of cards that have synergy with jeskai ascendancy or the overal gameplan i'm trying to achieve, this is what i trimmed it down to.
Battleplan etc:
Earlygame just play cards where needed and try not to run out too fast. 2 1/1 tokens for 2 mana is not that great.
Once Jeskai Ascendancy is in play, it all changes. The deck transforms into a midgame beatdown deck relying on synergy and tokens. And don't worry, fail to succesfully play and keep Jeskai Ascendancy is in no way the end of the game. Unlike the combo version, this deck is very much capable of grinding out wins on it's own. How often havent you seen turn 2 Young Pyromancer, turn 3 Dragon Fodder+Lightning Bolt taking on a commanding position in the game.
The plan is to burst tokens when the board looks advantagous. It's a fine line between keeping tokens up and waiting for Jeskai Ascendancy and Burst of Speed.
Short example:
T1 land
T2 land+Young Pyromancer
T3 land+Jeskai Ascendancy
T4 land+Dragon Fodder+Lightning Bolt+Burst of Speed
1x 5/4 pyromancer + 5 goblin token (4/4, 4/4, 3/3, 2/2 and 1/1) with haste untill end of turn. That's quite some power to swing with, not to mention bolting for 3 dmg on some defence or face. This also get's you 3x "draw a card, discard a card" from jeskai to set up your next turn and/or dig for something during the burst.
Sample game vs Abzan:
Once upon a time i managed to get T2 Young Pyromancer out which immediately got killed by Abrupt Decay, T3 Monastery Mentor was allowed to stay, as the opposing abzan player decided to play and buff his Scavenging Ooze to a 3/3 on my dead pyro putting him on 21 life. T4 i missed my landdrop, forcing me to choose between bolting the ooze or dropping Jeskai Ascendancy. I went with jeskai, generating a 1/1 token with prowess. He responded on his turn with a 3/3 scavenging ooze swing and a Kitchen Finks putting him a bit ahead (17 vs 23). T5 got my 4th land. I started with a Gather the Townsfolk generating a 1/1 monk token, 2 1/1 human tokens and buffing the mentor and the other token up to 4/4 and 3/3 respectively. Continued by bolting his ooze, generating another 1/1 monk, buffing the mentor to 6/6, 1 5/5 monk token, 2 2/2 humans and 1 3/3 monk. On my final red mana Burst of Speed came out, generating yet another 1/1 monk, buffing the rest to 8/8 mentor, 7/7 monk, 5/5 monk, 3/3 monk, 3/3 human, 3/3 human and giving the whole lot of em haste. Went in with everything, and after the mentor got blocked by the finks to see him get yet another 2 life, we started actually tallying my swing. After about 3 minutes of counting +1/+1 triggers he conceded after seeing his board being empty to my remaining 17 life and 6 1/1 tokens and his lifetotal dropped to 3.
Obviously chances are you won't have 4 lands and all those card in that exact order. But thats why this version is better then the alternative jeskai combo. 1 turn later, i still get a solid board filled with tokens, miss a landdrop, jeskai can dig, need defence, spam some tokens. Burst doesn't kill, just play 2 noncreature cards and swing with tokens that survived last turn and see them turn into 3/3's. Don't have burst of speed, spam the tokens anyways, swing on your next turn after bolting his face. Don't have jeskai? Intangible virtue is a fine 2nd making every token you spawn 2/2.
Lands:
Okey, so i really suck at the whole landbase building. Here's what i came up with so far. The only 2 cards that actually require U are Jeskai Ascendancy and Electrolyze. Both costing only 1 U and a CMC of 3. So there is no rush in actually getting islands. Glacial Fortress and Sulfur Falls should be more then enough.
Since there are no 1-drops i prefer those 2 and Clifftop Retreat over fetchlands. If need be, i'll play them tapped turn 1, but how hard can it be to hit 1 mountain or plains?
Questions:
Should i play countermagic to protect Jeskai Ascendancy? It would take up at least 4 slots and probably more, and would require a more blue/diverse landbase.
I absolotely LOVE Lightning Helix and Electrolyze but perhaps i should focus on 1-mana burn?
Do i need card advantage to keep my token engine up and running or trust in the deck to finish before, say, turn 8?
How hard would it be to get 5 tokens up at turn 5? Contemplating using Burn at the Stake as a little sideproject.
In what order do Jeskai Ascendancy and Young Pyromancer's "on cast" triggers resolve during my own turn? Do i get priority to make pyro trigger before jeskai, effectively giving the new token +1+1 untill end of turn?
More to come... development in progress.
Synergies, parts of the deck, etc:
Young Pyromancer+Monastery Mentor= 8 creatures that make a token on pretty much anything you do.
Dragon Fodder+Krenko's Command+Gather the Townsfolk+Lingering Souls=12 sorceries that make 2 tokens, this becomes 3 tokens with one of the forementioned creatures.
Intangible Virtue+tokens= 2/2 tokens
Jeskai Ascendancy+noncreature spell= +1/+1 creatures untill end of turn
Burst of Speed+said pumped up tokens= give them all haste
