For “Grisly Guardian” (a black creature that triggers on toughness change), similar cards in black:
- “Deathgreeter” — Gains life when creatures die.
- “Diregraf Ghoul” — 2/2 zombie for 1 black mana.
- “Syr Konrad, the Grim” — Triggers when other creatures die or leave your graveyard.
For “Group Hug” effects (usually in blue/green/white):
- “Howling Mine” — All players draw an extra card.
- “Kami of the Crescent Moon” — Each player draws an extra card on their draw step.
- “Rites of Flourishing” — Everyone draws and can play an extra land.
Reason: These examples provide similar effects in the same colors—tokens, group benefits, and triggered abilities.
