Don't know if you have a plan here (being it flavor or something).
I adapted a deck i own, so it fits your budget.
Heroes
4 Favored Hoplite
4 Lagonna-Band Trailblazer
4 Akroan Skyguard
4 Phalanx Leader
4 Vanguard of Brimaz
4 Abzan Falconer
4 Ajani's Presence
4 Defiant Strike
4 Gods Willing
4 Feat of Resistance
20 Plains
This is a standard version. You can look probably into more interesting spells in modern.
It's fun to play, resilient and versatile (use gods willing/feat of resistance to protect from damage/bounce and ajani's presence against board wipes).
The star of the company is obviously Phalanx Leader, any spell you target him with grants counters to all your other creatures.
Then you have Abzan Falconer to get them all airborne.
Maybe this is lacking some spells that target two or more creatures at a time like Dauntless Onslaught so you can, for instance, targe Vanguard of Brimaz, make a cat soldier and then place a counter on him from the Phalanx Leader (you can decide to put Vanguard's ability resolving on the stack before Phalanx's).
