• Balance out color counts.
• Underworld Dreams is much more fun that Hymn to Tourach.
• Let go of some unplayable cards.

• Ebon Praetor + Breeding Pit combo is in
• Ramos, Dragon Engine as an enabler, and Garth One-Eye + Cromat as improved payoffs for WUBRG.
• Squandered Resources combos with Howl From Beyond or Knight of Autumn.
• Upgrade to power level of gold cards - especially in green color pairs.
• Chatterfang, Squirrel General and Squirrel Mob for some token and squirrel synergy in green.
• Miscellaneous upgrades to brown knick-knacks.

Add the cool Alliances mono color utility lands to celebrate my acquisition of Lake of the Dead. A couple of miscellaneous fun card upgrades are in here, too.

Elven Lyre and Goblin Lyre ended up be underwhelming, so they seemed like perfect candidates to pull in order to make room for Voltaic Key, which has some cool interactions (ex. Phyrexian Colossus). Serrated Arrows will be useful for fixing removal, especially in aggro decks.

Slimefoot, the Stowaway, Knight of the Reliquary, Mortify, and Consuming Aberration are powerful Time Spiral Remastered cards to replace some of the weaker gold cards, which should ideally be a pull into that color pair. Scaled Wurm is out to help make room. It's sad, since it has the cool and iconic art, but it's underpowered. Zulaport Cutthroat swapped in for Mire Shade to fuel some sacrifice/removal synergies.

Erhnam Djinn is in, because it rules and is a classic. Fungus Elemental is out, since it was the most dispensable green 4-drop. It's worth reconsidering bringing back if we think we need synergy for Knight of the Reliquary, though.

Mystic Remora is a super cool and effective 1-drop for blue. Merfolk of the Pearl Trident is weak, and swapping Vodalian Hypnotist in for Magus of the Unseen keeps the Merfolk count even.

Curiosity in as a great card draw engine. Tangle Kelp out because it doesn't do enough, and requires memory energy.

Squirrel Wrangler swapped in for Elder Druid, because it's just too rad with Deranged Hermit.

Give up on zombies, and some fun stuff and classics

It is a really weak payoff for 5c.
