Equivalent cards (mono-green, protect green spells/creatures, or pump effects):
1. Cavern of Souls (protects creature spells from countering, any color deck, often used in tribal)
2. Destiny Spinner (makes creature and enchantment spells uncounterable, also a mono-green effect)
3. Asceticism (protects all creatures with hexproof, regen, mono-green)
4. Veil of Summer (protects against blue/black, draws, cheaper, mono-green)
5. Vexing Shusher (makes a spell uncounterable, Gruul, but can be played in green decks)
6. Steely Resolve (gives hexproof to chosen creature type, mono-green)
Reason: They share uncounterable or protection effects for green creatures/spells or similar tribal support.
