Thranduil's Company

Gone Fishing can blink two lands to trigger Thranduil's Company twice, distributing four +1/+1 counters at instant speed and granting vigilance to the targeted creatures.

Silvan Reveler is the additional Elf needed to unlock the Company's extra land play, and both that land play and a land put onto the battlefield by the Reveler's loot trigger activate the Company's powerful Landfall ability.

Mirkwood Pathmaker is another Elf that enables Thranduil's Company's additional-land ability; each extra land then increases Pathmaker's base stats and can also place two +1/+1 counters on it through Company's Landfall trigger.

Thranduil's Company enables additional land plays while both cards reward every land entering: Dancing creates a Bear and the Company adds two counters and vigilance to a creature.
