My best advice to you is to approach Dragons Maze holistically and trade for the cards that appeal directly to you
Cards like Gravepurge get good in this deck
You can pay 4 mana to cast it, or you can pay 4 life if you control a swamp
Once there, you can safely tick up those loyalty counters until you choose to either draw a bunch of cards or get a bunch of mana
(Choose any number of permanents and/or players, then give each another counter of each kind already there.) Illustrated by Anthony Palumbo Standard Not Legal Alchemy Not Legal Pioneer Not Legal Historic Not Legal Modern Legal Brawl Not Legal Legacy Legal Comp
Whether it actually gets used in Standard is not my realm to determine, but since it first showed up in Magic 2015, weve seen it appear once more in Magic 2019, as well as in the form of a judge promo, an Amonkhet Invocation, one of those Wilds of Eldraine fancypants spells, and an even fancier-pants spell, and now, Foundations, both as a regular version and a pretty neat borderless showcase
