I double-checked this rule
How about a supplemental set like Modern Horizons 3
Creatures (31) 3 Goblin Vandal 4 Goblin Recruiter 4 Goblin Matron 4 Goblin Lackey 2 Kiki-Jiki, Mirror Breaker 3 Goblin Warchief 1 Goblin Sharpshooter 4 Goblin Piledriver 1 Gempalm Incinerator 1 Siege-Gang Commander 3 Goblin Ringleader 1 Skirk Prospector Lands (18) Spells (11) Sideboard Once you stack your deck, every Ringleader will hit four more Goblins, meaning you can basically just draw whatever sixteen Goblins you want (and thats not even factoring in Goblin Matron)
Well leave you to discover what these new and unique card types can do
This effect is simple, clean, and doesnt turn into a brick in your hand
The goal of the deck is to play creatures and slap counters on them with cards like Maester Seymour then reward you for doing so, drawing you cards with Bred for the Hunt, giving them keywords with Sphere Grid, or protecting them with Inspiring Call, all while your creatures to continue to grow and bash in for more damage
