Whenever you amass, you either create a 0/0 Orc Army token and put the specified number of +1/+1 counters on it, or you can put that many counters on an already-existing Army and it also becomes an Orc in addition to its other types
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
My decklist shored up whites weaknesses by leveraging the draw from Conjurers Mantle and Rammas Echor, while ensuring we could survive long enough with lifelink synergies
You'll put a +1/+1 counter on both creatures
Like the other Mega Pokmon cards that came before it, its highly probable that the new Mega Charizard card can find its way to the various Standard meta decks
What makes Solitude so powerful in Modern is that the format is slow enough and the lack of Wasteland means that youre usually hardcasting them instead of evoking them, which when you combine it with blink effects like the previously mentioned Ephemerate and Yorion, Sky Nomad, is an extremely potent card advantage engine
