Thematically, youre building up the story of another character, taking a lowly Llanowar Elf up to a massive 10/10 creature, and now you can tell their exploits throughout time (or at least until you win the battle)
As expected, they usually occupy Esper or Dimir color combos and function best when youre drawing cards and taking extra turns
Empyrial Armor (Ext, S, Block) Arguably the best enchant creature in Magic history
We, that complain the EV of a set or pack is too low
The +1/+1 and haste will make it better than Fires of Yavimaya, and the additional options of Threaten or make a quintet of 4/4 Dragons are both really strong abilities too
A catch-up mechanic that doesnt completely kill the card when youre ahead is unheard of, and is something we need to see more of from Wizards of the Coasts design team
