>>14785039CARDNAME gains reach until end of turn.
Although some people would reccomend using "the beginning of the next end step" instead of "until end of turn".
My logic for the statting of this card:
White Knight & Black Knight both cost 2 coloured mana of their colour, are 2/2s & have 2 abilities. Thus, I had the paladin trade first strike for vigilance. He's not on a horse, or wielding a lance, he's a paladin, probably charging at those he shall smite, so I think it makes more sense than first strike. Plus, my inner-Melvin/Spike likes it for the self-synergy it gives the card.
It costs 2 different colours of mana, so I gave it another colour to be protected from. Didn't make sense for it to have protection from itself, and white and black share blue as an allied colour, and have no shared enemy colours, so he got to be pro-red & pro-green.
He costs 1 more than your normal White Knight/Black Knight, and it's coloured mana, albeit hybrid coloured mana so I gave him the tap ability. In my defense, it requires the target to be attacking or blocking, & I think if you're able and stupid enough to attack or block with this thing out, you're either stupid or well prepared.
