Call the Spirit Dragons (TDM 174)

Enchantment • Mana cost: {W}{U}{B}{R}{G} • Tarkir: Dragonstorm • Mythic

Dragons you control have indestructible.
At the beginning of your upkeep, for each color, put a +1/+1 counter on a Dragon you control of that color. If you put +1/+1 counters on five Dragons this way, you win the game.

The essence of Tarkir was shaped into draconic embodiments of the re-formed clans.
