Temur Bear HordesTemur Ascendancy Buy + Obelisk of Urd Buy + Words of Wilding Buy
: Put X 4/4 green Bear creature tokens with haste on the battlefield. Play this only when you draw a card.
Temur BurstTemur Ascendancy Buy + Saproling Burst Buy
The classic Fires of Yavimaya Buy + Saproling Burst Buy now comes with a Concentrate Buy tacked on. Should be essential for all Temur Ascendancy Buy decks.
Double-Up Freebie KillHeroes' Bane Buy + Corpsejack Menace Buy + Retribution of the Ancients Buy
Have all three on the battlefield. Pay : Target creature gets -X/-X equal to Heroes' Bane Buy starting number of counters then double them. Obviously you can kill something even bigger the next time and so on. There is no need to take ALL the counters off each time but I like the simple maths
Enfamil. ProSobee style.Deadeye Navigator Buy + Cloud of Faeries Buy + Altar of the Brood Buy
...derp derp derp...
...sub out Cloud of Faeries for Peregrine Drake/Great Whale/Palinchron, etc...

1. Cast Altar of the Brood first followed by Avenger of Zendikar and Deadeye Navigator
2. Altar of the Brood's effect is triggered because there are permanent that enters the battlefield.
3. Soulbond the Avenger of Zendikar and Deadeye Navigator.
4. Repeat step 2.
Ixidowny jr.Secret Plans Buy + Ixidron Buy
Play the plan: Ixidron and his 2/3er gang eating the opponents 2/2's.
Perhaps for an morph-deck?
Sprout Swarm AscendancySprout Swarm Buy + Jeskai Ascendancy Buy
Any creature with "tap: Add or any color" to put it off faster, Sylvan Caryatid is a good option...
Jeskai ArcanistJeskai Ascendancy Buy + Elite Arcanist Buy + Manamorphose Buy
manamorphose can be replace with evermind.
so basically draw your deck and each creature you control get +x/+x , so I suggest adding some storm or unblockable
