They can be played alongside high-cost cards in order to spend your extra ink and develop your board, they can get buffed by a Support character like Rolly and become a cheap way to trade up into bigger threats, and Lucky can discover them when you use his ability Good as New, making them more valuable in your deck than in your hand

Additionally, if you can get Cloud up to seven power, he will eventually start chugging out mana as well through Treasure tokens, allowing you to more easily equip the rest of the creatures on the field
