MTG Salvation

If I control Immaculate Magistrate and cast eyeblight's Ending, While that is on the stack can I tap Immaculate Magistrate to give itself 2 counters, or would it just be 1?

Each Elf you control mean each permanent you control with the subtype elf.
So you will only get one 1 in this case.

In short: one.

There's a rule in Magic - I'd have to dig in the Comp Rules to find it for you - that basically states that wording such as on Immaculate Magistrate is meant to imply Elf permanents you control.

The word "control" on the card refers to a permanent on the battlefield. A tribal card is not a permanent on the battlefield, so it does not count as an elf you control.

Here is the ruling on tribal instants

If a spell asks whether you control a Goblin, it's asking whether you control a Goblin permanent. It won't count Goblin spells you control (including itself).

You control one elf, so you get 1 counter.

Thanks guys!
