Well, theyre helmed by Aurelia, the Warleader for the most part, though there are some Isshin decks that like to play with extra combats now too
As such, in calculating the value of the cards in the set, I'm trying to use the number that I realistically think I can get for the card tomorrow (this is important because new sets tend to decrease in value quickly)
It doesnt specify that the creature needs to tap for mana, which means Eldrazi Scion and Eldrazi Spawn tokens benefit from the buff
Fake cards' graphics/text is usually blurry, the colors look bleached or are simply off (too much red in like 90% of the time)
Magic players know this as Summoning Sickness
You dont have to worry about investing mana into Walking Ballista at all, and milling it with cards like Malevolent Rumble does the trick just fine
