With all the ramp spells available to us, we arent going to add more lands here, but lets swap out the play-extra-lands cards in favor of cost reducers and group hug ramp
If you want to take it even further then I recommend adding protection like Pyroblast, more tutors like Doomsday, more fast mana like Mana Crypt, etc
Edicts are your best friend for Glissa's triggers
The trio of colors represented in Revival Trance is also very well-suited for a Legendary Matters theme, and with a few adjustments we can convert the deck over fairly easily
The bundle contains 9 Foundations Play Boosters, 16 Traditional Foil Basic Land cards, 16 nonfoil Basic Land cards, 1 oversized Spindown life counter
It can protect anything be it Enchantment, Creature or even Planeswalker (though it wont stop combat damage)
