If you grant your creature protection from white, for example, you wont be able to target it with any of your other white cards
There's a twist, though: If a creature with +1/+1 counters on it gets enough -1/-1 counters to kill it, it dies before the two counters have the chance to cancel out
The first official serialized cards in MTG were the serialized retro-frame artifacts found in The Brothers War collector boosters
Each Collector Booster contains 15 Magic: The Gathering cards and 1 traditional foil double-sided token, with 2 Foil-Etched cards and 10 Traditional Foil cards in every pack
5/4 Green is generally the best at hating on artifacts and enchantments, but the possibility of reliable, repeatable, and protected removal
The decks are genuinely a ton of fun to play, but thats not the only reason theyre so great to play with
