You could focus on that they have an ability that works in the graveyard
You can bet the stock of other two mana counterspells like Mana Leak and Remand will be dropping hard, and that's to say nothing of Logic Knot, now that Counterspell is back
If they do, you draw that many cards, create that many tapped Treasure tokens, then lose that much life
Its +1 is only card advantage if you discard creatures (hard to do after casting a 6-drop), its -2 requires setup to do anything, and the -7 requires three full turn cycles to pull off
This mainly comes up with the three cards that each generate three tokens at once: Bestial Menace, Trostani's Summoner, and the new Somberwald Beastmaster
The lesson here is one we've seen before: initial hype prices for modern Pokemon sets are almost always inflated
