Instead of dealing with the players Commanders, try and work your way around the other cards that enhance the Commanders powers
Creatures (6) Arboreal Grazer x4 Subtlety x2 Instants (18) Lightning Bolt x3 Counterspell x4 Planar Genesis x4 Expansion / Explosion x3 Nexus of Fate x4 Sorcery (4) Gates Ablaze x4 Enchantments (7) Guild Summit x4 Wilderness Reclamation x3 Lands (25) Azorius Guildgate Breeding Pool x2 Gruul Guildgate x4 Island Izzet Guildgate x4 Misty Rainforest x2 Scalding Tarn x2 Simic Guildgate x4 Steam Vents x2 Thran Portal x3 Sideboard (15) Consign to Memory Haywire Mite x2 Spell Pierce x2 Swan Song Damping Sphere x2 Dismember x2 Gatebreaker Ram x4 Force of Vigor I won't pretend that this is the most competitive Modern deck in the world, but it's a riff on a deck I loved playing in the Standard, and it gives you a pretty good idea of how a gates deck wants to play
Awaken the Woods definitely offers a very strong effect, but it will most likely see play only in Commander format, where there is no such thing as too much mana
CGC notes "Mystery Booster (Test Card) Special." The Mirrored Lotus Test Card is a regular card that has a sticker of the Mirrored Lotus stuck on the front
Always check the cards condition closely, looking for any scratches, bends, or whitening on the edges
