Huh, I actually associate
Weezing with mass spread damage and
Greninja with a free Retreat Cost.
As others have already pointed out, the new
Greninja promo might actually make sense in a
Greninja BREAK deck; its damage spread that isn't Ability based. Of course, its only 20 damage and you're giving up a chance to shut down Abilities or just hit harder or (in Expanded) use the regular Water Shuriken Ability.
Weezing is disappointing, but I suppose for filler at least its competent. Levitate on something with a high Retreat Cost is kind of nice, kind of not; better than wasting it on a card that doesn't really need it, but they could have just opted to give a
Weezing a free Retreat Cost and then a different Ability, a second attack, or a better lone attack. Smokescreen can be great on a Basic you use to open while doing some damage, but not on a Stage 1 with no other tricks. Plus even if everything else about the card remained the same,
Smogscreen should have been the attack. =P
