I don’t understand why creatures with hexproof are immune to indirect effects of cards, like displacement wave or claustrophobia. Is this intentional? If so the in game description is misleading, not to mention it isn’t congruent with the actual card game.
Yes it is intentional.
Not everything is a 1 to 1 match, for obvious reasons.
For instance, a lot of the “on spell” abilities in MtG were very powerful, but here they kind of suck.
And here the creatures are often much fatter!
