These are some good suggestions, I actually wanted
urborg elf instead of satyr but I couldn't remember it's name for the life of me so I just put
voyaging satyr instead. I thought
I had
herald's horn in but I must have taken it out for something else, the main reason I'm playing
rat colony instead of
relentless rats is that they are cheaper per rat and bringing them down to one mana is great. I can't wait for magical christmasland where I have a
beast whisperer out along with a
carnival of souls and anything that reduces the price of my rats to one black mana (
herald's horn,
jet medallion, monument) and then storm off with rats lol.
I consciously didn't put in things that would increase my rats toughness so that umezawa and
skullclamp would be useful so I don't think I'll put something in that just gives +1/+1 because I think that their abilities are far stronger/more relevant. That said,
coat of arms makes such a huge impact that I think it is worth adding.
Ratcatcher seems like a good addition to the top end of my curve and a good way to consistently get more rats, I'll definitely consider it.
The mana base will probably be upgraded beyond basics at some point but I find it the least exciting part of deckbuilding so I'll probably put it off a bit lol.
Marrow gnawer seems great! Another reason I used
rat colony over
relentless rats is that it scales with all rats not just other rats of the same name.
I decided to use damia as the commander because I wanted to be in Sultai and she seemed to be able to constantly draw me more rats, also with so many rats I'm
bound to be a bit light on other types of cards so she helps me dig through my deck for other cards a lot better.
I definitely like
dreamscape artist as ramp.
Murder is not a great card as it turns out, there are a lot of things better than it and the ability to get rid of enchantments and artifacts is definitely relevant. I may also consider some counterspells, mainly to help deal with board wipes but because they let you remove a threat before it even hits the field.
