Basically the strategy is a more restrictive value based around a card type to get the most value out of the deck
Spirit Water Revival, from Avatar: The Last Airbender , has a huge ceiling: you reshuffle your graveyard, draw a huge amount of cards (nine in total!), and on top of that you get the effect that gets Spirit Water Revival into this ranking: no maximum hand size
Most aggro decks in black will just run him
Assemble the Legion slowly gives you more tokens every turn, Rabble Rousing gives you a 1/1 token for every creature you control that is attacking, and Krenko, Mob Boss creates Goblin tokens for every Goblin you control when you tap it
Should you get enough mana to Harness it, this card becomes even more obscene
Heliod, the Radiant Dawn / Heliod, the Warped Eclipse This was the card that surprised me when I started to go through all the Theros gods
