Hello fellow Wyleth, Soul of Card Draw player!

I'm glad you got both Wyleth's and Aesi's precons for a good price. They are reeeeally explosive in gameplay with a few upgrades.

I play a lot of this bad boy, and I want to suggest some swaps below 3 USD for you to take it to a higher ground:

First of all, the ramp. I found out that 2 CMC, untapped ramp is the best for Wyleth. Since he draws so many cards, he can chain rocks and voltron pieces in the same turn, so his next turn is even more explosive than the last one. I almost always have more mana than the Green decks in my pod.

• Oreskos Explorer -> Dowsing Dagger  ^Flip (you can get this to flip easily on turn 4)
• Kor Cartographer (too slow) -> Arcane Signet
• Emeria Shepherd (Voltron decks need a REALLY good reason to run cards above 3 mana in their builds) -> Starnheim Courser (this allows you to storm out of control. It is another body to voltron if needed)
• Keeper of the Accord (the token is irrelevant for you and, with Wyleth's card draw, you won't be behind in land drops) -> Talisman of Conviction

You should run boardwipes that hits your stuff the least:

• Tragic Arrogance (no need to destroy your own stuff) -> The Eternal Wanderer's ult
• Disenchant -> Heliod's Intervention
• Ironclad Slayer (we'll compensate him in the landbase) -> Vandalblast

Also, you can streamline your removal package. All of those are fetchable by Sunforger:

• Wear / Tear (good removal, but you already have more flexible options) -> Reprieve (that's one hell of a card to fetch out with Sunforger)
• Hyena Umbra (still vulnerable to exile and bounce effects) -> Blacksmith's Skill (all-around protection)

More/better auras and equipment

• Temur Battle Rage is a cute combat trick, but Battle Mastery is permanent and triggers Wyleth.

• Same to Reyav, Master Smith: one thing I've learned is to only rely on other card types for things Auras and Equipments can't do. All That Glitters, most of the time, performs better than him.

• Infuriate -> Thran Power Suit (same reason as above)

• Adeline, Resplendent Cathar (lost to her yesterday, but she does not give value here) -> Empyrial Armor (Wyleth gets huge with this)

• Kor Duelist -> Empyrial Plate (same as above)

• Ring of Thune -> Shielded by Faith

• Gimli's Axe -> Maul of the Skyclaves
• Argentum Armor (too expensive to cast) -> Mirror Shield (hexproof is crucial on a Voltron build)

Cheating equip costs

• Brass Squire (having to wait a turn to use his ability is rough) -> Ardenn, Intrepid Archaeologist
• Kemba, Kha Regent (too slow for a Voltron build) -> Bruenor Battlehammer

If you really need to protect yourself against attacks, Ghostly Prison is a way better Palace Guard.

More utility lands

• Minas Tirith (Wyleth draws enough cards already. Also, most of the time, you will only have a single creature on the field) -> Axgard Armory (tutor on a land)
• Plains -> Sejiri Shelter  ^Flip (a protection spell stapled onto a land)
• Mountain -> Buried Ruin (Ironclad Slayer's removal is avenged!)
• Plains -> Mistveil Plains (it can return instants back to the deck to be fetched again by Sunforger)
• Mountain -> Great Furnace (synergy with All That Glitters and Puresteel Paladin)
• Plains -> Ancient Den (same as above)
