MTG Collection Builder
The design team seems to be content with only one or two Supporter engines dominating the format for years on end, and with supporting effects like Rain Dance coming and going

One is Aggro Loam, which floats somewhere in the second or third tier of Legacy

an instant Synchro enabler, and theres a variety of targets for her including: 1 X-Saber Airbellum (Level 3 Tuner and Hand Control tool) 2 Ryko, Lightsworn Hunter (Level 2, being a Non-Tuner, it can make a Synchro 5 with just itself and Airbellum, or other monsters depending on your other levels on board) 3 Neo-Spacian Dark Panther (More of a fringe pick, but being a DARK and a Level 3 it has some desirable traits, and its ability to steal effects can be hilarious) 4 Gladiator Beast Samnite/Test Tiger (In Gladiator Beasts , you can either summon 2 Samnite for a double tag-out, or Samnite and a Tiger for a free, easy tag-out) Package requirements: 1 Rescue Cat (Limited), 1 Summoner Monk, Targets based on deck choice(Usually 2-3 of each Airbellum and Ryko, some opt for 1 Dark Panther, and for Gladiator Beasts, you only really need Samnite and Test Tiger) Best in: X-Sabers, Gladiator Beasts, and decks running Hamster/Ryko/Airbellum

Cards that are in the Mystical Archive from Strixhaven , as a separate example, are not Masterpieces and are their own type of card, though they are similar
