Coretapper Discussion

Great article as always! I agree that this set is underrated, and one of the cards you highlighted, Magistrate's Scepter is my favorite of the bunch!

I discovered it while looking for the most broken thing I could do with the sick Mimic Vat + Coretapper combo, and it certainly stood out! A 3 card combo, sure, but each piece was so cheap, and for 3 mana a turn, you never let your opponent take another turn! I still consider it the most underrated card ever.

Once again, thanks for the article, I'm looking forward to the next one.

I loves Mag's Scepter, when I first saw it my Coretapper 's got frisky!

I like Energy Chamber + Lux Cannon A good combo with so much untapping. These with Coretapper can make for a lot of fun multi/Inf use with

Magistrate's Scepter = Inf Turns.

Everflowing Chalice / Astral Cornucopia . = Aether Vial like utility.

Coretapper , Energy Chamber , and Vedalken Infuser or are straight up proliferate effects just better you think?

Most of the big ones can be cheated out somehow, or cost reduced to come out earlier. They can however be slow without the right set up. Like Mage Ring and Col. Syria need Voltaic Key or Unwinding Clock to be more useful. Perhaps I could lose a few though, I had thought of including Bosh with them so they could swing then fling. Felt like it required more dedication to it though.

Love the Bastion and Sage for additions. Lux Cannon is also a nice addition for our removal suite.

As for lattice, that is far outside what I'm willing to pay for colorful cardboard. Tyrant is in the main, but I've kinda been wondering if he's worth it without lattice. S. Tithe is a nice addition, the tutors could also improve plays. I just dont want to get to a point that it's the same play every game. As for owning the cards, I make decks before I purchase to try and work out kinks before wasting money. Also I try to keep in it the 200 total range so it's not impossible to put together in the real world.

Thanks all for the suggestions, its very much appreciated.

Coretapper helps with charge counters.

Surge Node and Coretapper are basically mandatory for this archetype, and its worth remembering that WOTC are balancing around Everflowing Chalice and Astral Cornucopia pumping out a lot of mana.

If you are seriously looking at making it work in a super budget way, Throne of Geth and Tezzeret's Gambit should be the top end of your deck, while the rest aims to win before vast amounts of mana would have been relevant. This means focussing on one clear strategy- I'd reccomend Shrapnel Blast / Atog / Slag Fiend , but Shriekhorn mill is also an option.

If you are prepared to drop another ten bucks, you can make something fantastic built around Saheeli, Sublime Artificer who releases soon- copying onto Surge Node is strong.

Every part of this works.

You can always choose to pay for , unless the card specifically states otherwise.

There is also no prohibition on putting charge counters on Astral Cornucopia after it enters the battlefield, so you will be able to add them with Coretapper .

Finally, abilities that do not require can be activated even if the permanent is tapped. So, with Coretapper , you can tap it to put a charge counter on Astral Cornucopia , then sacrifice it to add two additional charge counters, so you have a total of three charge counters on the Astral Cornucopia that you paid for.
