Silver Myr add U to your mana pool rulings mana ability faq magic

[Crocodile]

Is the ability of Silver Myr considered a "Mana Ability"?

Like can it be targetted by the ability of Ouphe Vandals?

[Arix]

An activated mana ability is an ability with three requirements:
1. It could add mana to your mana pool.
2. It has no targets.
3. It's not a loyalty ability.

Since Silver Myr's ability meets all those requirements, yes, it counts as a mana ability.
