There have been a lot of powerful hate cards against red Chill, Warmth, Sanctimony but I think CoP: Red was both the best and the most iconic
They are Vrondiss, Rage of Ancients (a Dragonborn Barbarian, leading the red/green Draconic Rage deck), Prosper, Tome-Bound (a Tiefling Warlock, helming the red/black Planar Portal deck), Sefris of the Hidden Ways (a Genasi Wizard, leading the White/Blue/Black Dungeons of Death deck), and, finally, Galea, Kindler of Hope (a Half-Elf Paladin, topping the White/Blue/Green Aura of Courage deck)
Reshiram is best used as a mid-game attacker who helps another attack, or as a late-game sweeper to take decisive knockouts
Invasion of Ravnica is the only colorless battle
You might be thinking But Tommy, isnt considering the effect on the card and the purpose of that card the same thing? There is a key difference between just understanding the effect on a card and the purpose of the card
The first is that on your end step, you can give away a creature you control with two +1/+1 counters and then it's tapped and goaded for the game
