What an edge is, and what it is not

Impact Tremorscares about
Edge. When a creature enters thanks to Krenko, Mob Boss, Impact Tremors deals 1 damage.
Farseekproduces
enters · land
Enduring Couragecares 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.
