Coin of Rortama
Enchantment
{1}: Put a coin counter on Coin of Rortama. This ability costs {1} more to activate for each coin counter already on Coin of Rortama.
Sacrifice Coin of Rortama: Search your library for a creature card with power less than the number of coin counters on Coin of Rortama and put it onto the battlefield. Then shuffle your library.
If you removed the "more to activate" and it searched for CMC, then I think it would be quite a powerful fetch that ends up more balanced.
