Thoughts on tribal rats commander deck?

{"ops":[{"insert":"I think you need more sources of evasion. I see you getting chump blocked a lot.\n"},{"insert":{"card-link":"Cover of Darkness"}},{"insert":" "},{"insert":{"card-link":"Rogue's Passage"}},{"insert":" "},{"insert":{"card-link":"Shizo, Death's Storehouse"}},{"insert":" \n"}]}

{"ops":[{"insert":"I like the theme. Rats are a cool tribe, and discard can be powerful. I see you have some cards that synergize with getting lots of rats on the board, and youj say the point is to swarm the opponent. Here's what I see after taking a look...\n\nThe main way you have of swarming the field is with your commander's activated ability. In fact, I don't really see any other ways for you to reliably make lots of rats in one turn. This means, in order to swarm the board with rats, "},{"attributes":{"bold":true},"insert":"you need to either be activating you commander often, and or playing lots of rats from your hand."},{"insert":"\n\nStarting with the second option - playing lots of rats - I can see you getting 5-6 rats by turn 6, but then having an empty hand, with no way of drawing more cards. One board wipe and you're dead in the water. More repeatable card draw (like "},{"insert":{"card-link":"Phyrexian Arena"}},{"insert":" which you have, "},{"insert":{"card-link":"Morbid Opportunist"}},{"insert":" ), or engine pieces would be nice, to"},{"attributes":{"bold":true},"insert":" fuel the swarm"},{"insert":". You do have some cards that make rats when creatures die, but no reliable way to sacrifice your own creatures. If you want to make your engine around death triggers, also try adding some sac outlets.\n\nIf you want to rely more on your commander to power out your swarm, I think having more protection would be helpful. Especially because your commander is 5 mana. He's a strong target for removal since he's powerful (exponential joke ain't no joke,) albeit slow.\n\nI think you also need more killing potential. A couple more cards that can make you a ton of rats in one turn, and a couple more damage spells (like "},{"insert":{"card-link":"Ayara, First of Locthwain"}},{"insert":", "},{"insert":{"card-link":"Gruesome Fate"}},{"insert":") that scale with that strategy. If your card draw ends up being, sacrifice based, those big token generator spells can double as card draw.\n\nFor cuts, I would look at getting rid of some of your worse rats like "},{"insert":{"card-link":"Gutter Skulk"}},{"insert":" "},{"insert":{"card-link":"Ossuary Rats"}},{"insert":" "},{"insert":{"card-link":"Nezumi Bladeblesser"}},{"insert":" \n"}]}
