Bought all the cards for Modern UWR control and played it for the first time at FNM tonight. Went 2-1-1, Beat Merfolk and Tron, drew to Junk 1-1 and lost to UWR Geist. Quite happy with it, Blade Splicer definitely isn't awful but I need to play more to decide whether the more tempo version with Geist really is just better. Geist is definitely better in the mirror but against other decks 3 Blade Splicers + 4 Restoration Angels can still put on a lot of pressure and are much better on the defense.
The other route is getting some Cliques (which I should probably have anyway) and Kiki-Jikis and play the UWR combo/tempo list I've seen the winner of GP Antwerp is testing. I should probably not spend more money on Magic for a while though.
