What an edge is, and what it is not

Krenko, Mob Boss produces
enters · creature · token
Impact Tremors cares about

Edge. When a creature enters thanks to Krenko, Mob Boss, Impact Tremors deals 1 damage.

Farseek produces
enters · land
Enduring Courage cares about

No edge. It wants a creature entering, and a fetched land is not one.

What it refuses to claim

Ramp, removal and card draw are roles, not synergies — they make a deck work without pairing with anything, so they are counted as slots rather than drawn as edges. A card that refers to itself ("this creature", "this spell") is read as itself and not as a class. Where the rules cannot say something, the report says nothing: a missing claim is better than a confident wrong one.
