I'm talking about Yennefer's Invocation, Tibor Eggebracht and Vilgefortz.
Perhaps less so with Invokation, but she can still produces very powerful plays ( also she's not kept in check by a randomness factor unlike similar cards)
Tibor and Vilger though... In all the many, many many times I've seen another player use them, I don't think I've ever seen the "cost" effect of using them backfire on the nilgardian player. In pretty much every case, both cards have the effect of forcibly using an enemy card and negating it. I mean negating because this effect makes the enemy unable to use their active deploy abilities, not be able to use of their order or passive abilities, since those can be blocked by the row onto which they're spawned as well as not be able to execute the unit formations that some cards require.
In practice they have the effect of "get a 13 value card and waste an enemy card" and "destroy an enemy card at no cost and waste an enemy card" (two if you're playing emhyr). Am I wrong here? Maybe I am but it feels like these cards' effectiveness is far greater than what their cost would suggest. And that's just when treating their effects by themselves, they get even more powerful in practice when working in combination with the variety of other cards nilfgard has which have the "waste" effect.
