So I pulled some mostly random Magic: the Gathering cards together to make this D&D 5e magic item based on what their artwork looks like what effect they'd produce. It's mildly inspired by "The Deck of Many Things" but a lot more forgiving. This is my first time making an item like this so some feedback would be great if it is needed. If it looks interesting please go use it or change it to your liking. I'd love to hear stories of this item in action.
The Deck of Boons
Magic Item (Wonderous) Very Rare(???)
This deck of cards is stored in a very pristine deck box made of wood taken from the finest Arborean trees. It also has gemstones of various kinds embedded into it although there is usually at least one emerald.
You can use an action to draw a card from the deck, activating it's effect according to the "Deck of Boons Table" as seen below.
Any spells that are cast use Constitution as it's spellcasting ability, a spell attack modifier of your proficiency bonus + your Constitution modifier, and a Spell Save DC of 8 + your proficiency bonus + your Constitution modifier
