Hi guys
That is my list. A couple of notes
1) The deck is pure theory-craft built. I had not tested it before the event. It is mostly based on success over the last few months playing RUG with true name nemesis instead of tarmogoyfs to accomodate a local meta overrun by 4c loam. List:
http://mtgpulse.com/event/16761#236363 . It is not particularly rooted in 4c delver, and i think more of it as a u/r deck splashing deathrite shaman and abrubt decay.
2) The philosophy was to try to keep some of the power of the u/r delver lists running treasure cruise, while adding more grindy elements that gives a better miracles and combo matchup (shaman, decays, actual interaction beyond daze/force, sideboard)
The list obviously did some things right, but there were also some things i would work on going forward. In particular, because of the slow creature suite and the lack of stifle, it often felt like i was playing a slightly grindy controll deck, rather then a tempo deck. Specific observations:
A) Treasure cruise
This card was insane whenever i cast it. unfortunately it does not enable itself. I was often stuck with cruises without enough cards in the yard. This makes me feel like i should be playing more cantrips, either probe or thought scour
B) Creature configuration.
I am 100% sure that tarmogoyf is a terrible creature that i do not want in my decklist, because he gets trumped too easily by tnn and plowed all day long, i am however, not certain what to replace him with. in a meta full of Jund and 4c loam, i would certainly play true-name, but it might be that pyromancer is simply so synergistic with the cantrip plan that he is better. Snapcaster is also very usefull in a deck full of proactive 1 drop spells.
C) Spell snare/spell pierce
These were god-awfull for me all day. I don't remember a single time where i played them. They were primarily included in the list to give me combo interaction. They were bad already in the deathrite meta, but with treasure cruise they are even worse, because i want to cast my disruption pro-actively. I will be running thoughtseize going forward
D) Wastelands
I routinely sideboarded these out against combo and u/r delver to become more spell-dense. This makes me believe that this sort of deck, when playing as a treasure cruise deck, rather than as an agressive deck, might not want wasteland...
E) Manabase
The manabase is not optimal and collapses under a stiff breeze. This is even worse without stifle. Adding an extra land is certainly on the table....
Conclusions:
I feel like treasure cruise is one of the most powerfull cards in the format, and deckbuilding should start with 4 tc, and then work backwards as to how to enable it.
Next steps will be to experiment with embracing the cantrip tempo-controll role by cutting the dazes, adding more thought scours, probes and/or preordain, replacing snares and pierce with thoughtseize and operating with a creature suite with some combination of: 4 pyromancer, 4 snapcaster, 4 deathrite 4 true name nemesis and potentially delver.
I would be happy to hear your thoughts, comments or testing results. Please also feel free to throw any questions you might have. The list might not be well-tested, but many of the elements are based on lots of games with other decks, and i had quite strong reasons for chosing the exact 75 i did, even if i might do it differently tomorrow.
