mystery box booster mtg Magic The Gathering this edition delivers variety and surprise in every pack Magic the Gathering: Mystery Boosters

Normal Deck 9.3 3 [9231] JP168 Tri-Brigade Roar Quick-Play Spell If you control a Link Monster: Send 1 "Tri-Brigade" card from your Deck or Extra Deck to the GY, then target 1 Effect Monster on the field

it grants +3 Strength and Evasive for a turn

it loses ATK equal to this card's current ATK until the end of this turn, then banish this card until the Standby Phase of the next turn

since gravestorm is like normal storm, each copy resolves individually, so even discounting the ability to exile cards from our opponent's library, what we have is a card that forces our opponent to shuffle their library a whole bunch of times (once for each copy)

Thanks to a few people for sending in the Great Dash Pack news, although where the info is from isn't clear at the moment

The cost reduction applies only to generic mana in the total cost of legendary creature spells you cast
