Now, you can't redirect a Counterspell to counter itself after your spell resolves
If that explored card is a land, you can take a land from your hand and put it into play tapped
This is another over-tuned 3-drop that just embarrasses other creatures at the same point on the curve, and it can connect in combat to basically draw you a card with selection each turn

As for Runehorn Hellkite, I've never met a Wheel of Fortune I didn't like, and even though this one is pretty expensive at six mana, it also generates random value from the graveyard if you discard it to something like Survival of the Fittest and is uncounterable and instant speed
Hitting the five different mana values is easier than it might seem in a singleton format as long as you build your deck with a functional curve
