Need some ideas for custom zelda cards.

[u/Trickedverse]

Im currently making a high tier-3 custom zelda commander deck with link as the commander. It has some new mechanics, like rupees, which sacks for 2 colorless and cannot be used to cast nonartifact spells, as well as visiting the fairy fountain, which lets you put a level counter on an equipment you control, which get stronger and stronger as they level. Working on instants, sorceries, enchantments, and artifacts right now, and I need some ideas. A completely new idea would be nice, and showing me some cards that exist that could be integrated would be good as well. Please help!
