If you do, return that card to the battlefield under its owners control at the beginning of the next end step. You can also cycle it for three mana too, but the key thing here is just filling your deck with cards that cycle and strong ETB effects, and then just going absolutely wild
It will also end up seeing play in the myriad counter based EDH decks
Good examples are too numerous to count, even recently, but Calix and Ashiok are excellent examples, offering two potentially useful abilities relevant in different situations
low CMC mana ramp spells like Natures Lore and/or mana rocks like Arcane Signet and Sol Ring will take care of the latter
Overall not bad, and it should gain you some cards
Princess Power perfectly sums up the Amber/Sapphire deck, full of royalty like the foils Ariel Singing Mermaid and Mulan Considerate Diplomat
