Magic: the Gathering in the UK
* Cabal Therapy
* Fact or Fiction (and thus, I guess, Sphinx of Uthuun, kinda)
* Gifts Ungiven
What other cards are famously skill testing? Conundrum Sphinx when you both have one? Force of Will?
Don't they justify putting awful cards in packs by calling them 'skill testers'?
when has gifts EVER been skill testing... get my recoup, or eternal witness, or unburial rites, gg?
I would add:
Sensei's Divining Top
Umezewa's Jitte (knowing that you should be playing it)
Some good adds Pete but I think Gifts can be skilltesting. Sometimes the power level is off the charts and it is just silly but in, say, cube, you can give your opponent hard and interesting choices.

Preordain. If you disagree with this you are doing it wrong
Also Squadron Hawks are actually quite a challenge, ignoring pre ban caw blade
Tromp the Domains for peoples skill level of being able to read 6 mana sorceries with a text box
