rare gyarados pokemon card - 20/70 - Holo -Reverse Holo Evolves from Gyarados V Type Pokemon - Gyarados - 6/102

These special rewards offer players the chance to exchange the Wildcard for any actual card of the appropriate rarity

You can always fire it off to blank something that targets you, too, since it gives a player hexproof in addition to small creatures

This also means you can use cards like Elvish Reclaimer to sacrifice a land, and then play that land again from the graveyard, giving you more chances to trigger Titanias ability

With Tempest carrying a specific part of all the other heroes, it's like an Amalgam character comes to life

I will point out, agent lets you steal the best thing they could find, AND it has flash, so it is better than the cards you listed, but fair nonetheless
