saddle never happens

[Argstein]

has anyone ever seen it in action?

No, they are too weak to be playable for the most part

[chelle.belle.]

I've only seen it a handful of times and that was in non ranked play

[magnumaniac]

Can be quite useful in draft, but only the strongest ones see any play in constructed probably. Calamity or Bronco maybe

Depends on the card.

The one that creates a copy of a creature i see regularly, and i use the saddle effect on the Bushwagg mount that doubles 1+1+ counters if i can do so without it dying. Especially useful with Botanical Warrior.

All the other ones aren't really worth it compared to all the creatures with far better effects imo.

Limited mechanic is limited. Works great in those formats.

It's my least favorite of the new mechanics, but I wouldn't rule out finding something broken about it.
