"Learn from your enemies, but do not tolerate them."

Wandering Champion

Whenever Wandering Champion deals combat damage to a player, if you control a blue or red permanent, you may discard a card. If you do, draw a card.

Ultimate Masters

Fate Reforged

If the only blue or red permanent you control is a creature that’s dealt lethal damage at the same time as Wandering Champion deals combat damage, Wandering Champion’s ability triggers.

If you don’t control a blue or red permanent as Wandering Champion’s ability resolves, you can’t discard and draw a card. The blue or red permanent you control as the ability resolves doesn’t have to be one you controlled as the ability triggered.

Wandering Champion’s ability doesn’t trigger if you don’t control a blue or red permanent immediately after it deals combat damage to a player.
