I meant for yesterday’s and today’s questions to be flipped around, but oh well mistakes happen!
Not including MH3, because lets be honest its hard to find cards outside of that set to answer this question if its included, what was the best card printed this year?

If I'm going new cards I have to collectively say the surveil lands.

Simulacrum Synthesizer is one of my favorite cards printed this year, but I think the best card outside of the surveil lands is Three Steps Ahead, card is so versatile and I’m always happy to see it.

[[Sink into Stupor]] or [[Fell the Profane]] simply because I am a usability fan and these have made it into by far the most of my lists this year.

Yea there's a good case to be made for most of the mono-color MDFC's from MH3, with those two being the absolute best of the bunch.
Witch Enchanter, Boggart Trawler and Pinnacle Monk have all been good for me too.
And from the tapped two-color ones, waterlogged teachings and strength of the harvest have done bits as well.

It's a late game threat that costs colorless and has strong evasion and blocking. About the only decks that can't use it well are specific typal decks, extremely commander-centric decks, and [[lurrus]] companion

Legendary Creature — Demon Kraken
Companion — Your starting deck contains only cards with even mana values. (If this card is your chosen companion, you may put it into your hand from outside the game for as a sorcery.)

Companion — Each permanent card in your starting deck has an activated ability. (If this card is your chosen companion, you may put it into your hand from outside the game for as a sorcery.)
Abilities you activate that aren't mana abilities cost 
less to activate. This effect can't reduce the mana in that cost to less than one mana.

I'd honestly consider a 7-drop to be too costly for just a vanilla dork in most of my decks. It could in theory go into them, but more often than not it would be bad for the curve and playability of the list.

The surveil lands from MKM
Is it cheating to count 10 cards as one? Yes.
Were they the best cards of the year? Yes.
Is it a boring pick? Absolutely
