Super good card.. took a long time to become relevant, and it sucks that it is rotating very soon

here: Tinkmaster Overspark

This card is stronger than Hunter’s legendaries this set.

Would this trigger Mecha'thun before it enters your hand?  Or is it entering your hand resolved during the "Discover" phase?

no, you flipping bacon

The discover happens first, so it wouldn't trigger. If you discover Oblivitron off this without any deathrattle/mech minions in hand it would immediately be put into play

Tunnel Blaster clean the board i smell murlocs in the way :D

Cheat out a good deathrattle... seems good... That is if deathrattle is good

Shimmerfly value! Lol. I'm intersted in the crazy stuff Wild players will do with it. This is such a powerful effect that it's going to limit design space for all future deathrattle cards in standard. Not sure how I feel about hunter getting another goodie. At least deathknights are gone..

The fact that it's discover too really pushes it over the top. It means you can still play other less-value deathrattle in your deck without messing up big combos

I mean, I don't know about anyone else, but I'm either gonna spam 'Mind Control a random enemy for 3 and add a Sylvanas to your hand', or 'Summon Thaddius and add another Thaddius trigger to your hand' all the time. :D

Ah, there's always to choice of trying something foolish with Hakkar, if there was a way to reduce his cost anyway. Tracking could do to lower the blood count for one's own deck. Maybe Flark can make it work, but we'd need to be lucky enough to not draw Hakkar.
