I think well be fine

If you have other ways to give players mana, through cards that are normally considered group hug cards like Heartbeat of Spring and Dictate of Karametra, you can deal some incidental damage that adds up over time

Unless you open them yourself, they'll be snaffled up long before they get close to you

To keep your cards in the best condition long-term its pretty simple and not too expensive
