The non snow-covered swamps will be snow-covered as soon as I track down 6 more. The reason they're snow-covered in the first place is for Extraplanar Lens when I get one. Once I add that and Gauntlet of Power, any and all mana issues will be fixed.
For those of you with rules issues, my play group allows multiple Relentless Rats so yeah.
Massacre should be replaced by Decree of Pain. While Decree doesn't have a "free" version, it can't really be used in a way that is extremely effective (not to mention -2/-2 kills most of your own stuff all of the time). And, since I'm assuming you'll have tons of creatures when you Decree, you'll at least draw cards for them as well.
If I were going to mess around with Relentless Rats, I'd probably go all in on that plan...play around 35 or so and build around Thrumming Stone. Doesn't really leave room for any other creatures, but do you really need other creatures?
That makes for quite a different deck, but it might be fun.
on the subject of rats..I had the same issue having to buy the rats cost me a total of 55 dollars for my thrity rats.
I still haven't bought any rat tokens yet,but I think i'll buy jsut two to three and use dice to keep track for those with damage etc..
and as for an RR deck heres mine :
Ward of Bones
Sensei's Divining Top
Coat of Arms
Ritual of the Machine
Tendrils of Corruption
back on saturday I played this deck and came clsoe to winning twice. the frist a board wip killed them all and then i used Patriarch's Bidding to bring them back, but then my turn was over letting the next player who brought back his creatures and thanks to Akroma's Memorial his stuff had problack >_< so I got killed off sicne i only had 17 life.
But if i had been able to swing I would have done over 700 damage with RR's ablity alone
