As shards is the flashback draft this week on MTGO and also one of the community drafts I thought I would add my thoughts on this. This is not, in any way, to say that I am an expert in this format but it is probably my strongest limited set (perhaps equal with TPF).
As I mentioned in the community draft, I think the best decks are 5 colours, normally with a focus on 2 or perhaps 3 colours with a couple of splashes. Mana fixing should be taken early but there is plenty of it. You probably will only run 15 lands in your final deck because of all the fixing.
I did an online draft earlier and went 2-1 (and was annoyed that I lost which was mainly down to drawing 8 land in a row (not an exaggeration) in a 15 land deck in the final round). My deck was base
splashing the other 3 colours predominately for a
Fleshformer. I made a stupid pick early on expecting a
Fusion Elemental to wheel but it didn't. The guy who beat me (and won the tournament) was also 5 colour. My other two opponents were both jund.
Here were my observations/recollections which may be useful if anyone is drafting but may, of course, not be:
Necrogensis is a bomb uncommon. With the amount of unearth in the set this card is immense
Cycling cannot be countered - I completely forget this when running into a guy I knew had
Resounding Silence with a counter in hand and lost my two best creatures.
There is so much fixing. I ended up with one tri-land (
Arcane Sanctum, 2 Panorama, 2 Borderposts and 3 Land Cyclers)
Anything with protection from any colour is an auto-include. Chances are your opponents will play that colour
Similarly artifact and enchantment hate (at least up to 2 spells) can be included.
Anyway just my thoughts. At the time of writing I have just submitted my deck for the next draft and, yes, it has 5 colours (although the moutain is only for
