I looked at it and I have some info that may help. Your trying to run a proliferation deck so you need a way to give counters. I would take out the creatures like the hands and viral drakes and add ichor rat and blighted agents. Second, the inexorable tides are good enough so remove the spells that cost a lot, like the fuel on the sidebar and add counter spells from blue, and dash hopes from black. I would keep steady progress and grim affliction too. I would also use the contagion engine and clasps, Throne of geth and add decimater web. Add creatures like plague Myrs memnites to use the throne. The lands are not needed btw. If I designed a deck I would do: Contagion engine 4 Contagion clasp 4 Throne of geth 2 Decimater web 2 Memnite 4 Plague myr 4 Blighted agent 4 Ichor rats 4 Steady progress 4 Grim affliction 4 Counter 4 Smallpox 4 8 swamps 8 islands 60 cards and you should be set
