Steamflogger Boss

this is great for changelings, gives them all pump and haste come on?

what can i say it won me the draft to kaladesh block, i was 3 life from dying, then i played one of these after the two others i had and the +2/+0 for all my riggers and octopled contraptions made that game truly a memorable clutch for everyone at my draft 

There's really no reason to take it so seriously. The card is supposed to be funny; nothing more, nothing less. It's not supposed to be a good card. Not everyone in Magic only wants cards that work in tournaments. I know this might sound shocking, but some people actually play and collect just to have fun.

In any case, it's not like they're selling the card for $50. It's 50 cents, take it or leave it. Tournament people getting upset about this card is like any Magic player getting upset about a Yugioh card; it's not meant for you.

I love this card; it's exactly what the future-shifted set is supposed to be. It's something that doesn't make sense now, but the idea being it might mean something in the future. The idea behind the timeshifted cards was that you're randomly getting a card from a different time or universe, and this card fits that perfectly.

Good for shapeshifters, not much else. I bought a dozen on eBay on speculation... When (if?) this set comes out, it should be pretty good - AND legal!

The best card ever! (possibly)

The problem here is that the card here seems to allude to something in a future set that we're not yet aware of. Potentially good, currently bad. If it turns out to be awesome, don't be surprised if the card balloons in value.

A very large disappointment... This card is an admitted failure; Riggers will never be printed, and contraptions will never be assembled.
Gogo Future Sight design team, printing (almost) worthless cards at a rare spot...

I do admit though, that I would laugh hard if I ever saw a Changeling deck using these - so at least it's not completely useless... It can pump Changelings and give them haste, and it also has a very multicolor-friendly manacost.
But alas, if you haven't heard it years ago; this card's abilities regarding assembling contraptions will never be relevant in Magic, because no cards relating to that ability will ever be printed - that's what the Wizards staff have been saying at least..

Steamflogger Boss gets 2 stars for actually being useful in Changeling decks... but other than that ... nothing ... perhaps being valuable for being a fail?

They have got to do something more with these abilities they created in TimeSpiral block; Fateseal, Poisonous, Contraptions, Granduer, etc. or I will be gravely let down... especially seeing this flop being sold at this price w/o any practical application!? 3/3 for 4cmc for a goblin is actually pretty tough, but that isn't enough
