This deck worked rather well sometimes.  Its weakness was having its creatures continually removed by Toby.  And obviously, it wasn't very strong against flying either.  However a good hand could have you swinging for between 8 and 26 on turn three using combinations of Adventuring Gear + Marauder/Geopede/Lotus Cobra + Scalding Tarn + Harrow + more harrow?/Terminate/Doomblade/Disfigure/Drag Down + Explorer's Scope depending on whether you got enough mana to play them all.

But I'm destroying it since there are more creatures in R/B/G than I can put in this deck, meanwhile the G/W/U deck is suffering from lack of good creatures and/or landfall triggers, but no shortage of enchantments.
