edhseer Commander synergy, explained
Paste your list and EDH Seer reads the oracle text of every card, then shows you which pairs have real synergy, with the reason written next to each one.
Pairing. When a creature enters thanks to Krenko, Mob Boss, Impact Tremors deals 1 damage.
No pairing. It wants a creature entering, and a fetched land is not one.
Ramp, removal and card draw are jobs, not synergies. They help every deck, so we count them rather than pair them with everything. A card that says "this creature" means itself, not every creature. And when the oracle text can’t settle it, the report says nothing: a missing claim is better than a confident wrong one.
