In regards to the sideboard I fell that [Blood Moon] hurts you more than helps since it'll turn around 90% of your lands into mountains, also a couple of sideboard cards I like to use for my affinity deck here are [leyline of sanctity] & [layline of the void]. Sanctity deals with mill, burn, and in a way anything like Rack. While Void deals with dreadge and anything else that deals with the grave.

@ zyphermage I am thinking about swapping out the Memnites for Welding Jars, so I would be putting 3 Welding Jars and dropping a Springleaf Drum for the 4th Thoughtcast. I know you are in favor of running the 4th Signal Pest too, so I will drop one Welding Jar to include the 4th Signal Pest. What are your thoughts on Welding Jar in place of Memnite?

@ dementor922 Considering 99% of my deck uses colorless mana, I don't see what the problem is. I can use red mana to summon my creatures. Additionally, things like Mox Opal & Springleaf Drum will still allow me to tap for any other color of mana I would need. Both Leyline of the Void and Leyline of Sanctity are good cards, but not necessary for me to win. My sideboard addresses many of those types of decks already. Ethersworn Canonist slows down spell heavy decks, preventing them from casting lots of low cost spells, same for Blood Moon. Spellskite can catch Lightning Bolts all day long. Both Grafdigger's Cage and Relic of Progenitus can shut down graveyard tricks. Overall, my sideboard is well designed to handle many of the threats, and I don't need to mulligan to get those Leylines in my opening hand to benefit from them.

Thanks for the +1 and the comments.

Memnite really has always to me just been a free drop add 1 to cranial, and welding jar still does that. You have 15 attackers with evasion, and so I think dropping a few attackers on the ground to keep the creatures in the air alive is fine.

A welding jar in play will usually get more affinity for longer, because they will possibly hold back on an ancient grudge or whatever else, since it gets nullified by the welding jar. They may use it just to make you sacrifice the jar, in that case a 0 drop for their destroy artifact/creature card is still a win.

I agree with zyphermage, the Welding Jar is the best bait in the game for Affinity. I've read a few articles that touch on the "political" aspect of Magic, and the Jar does it perfectly. I'll spare you a lengthy description, but basically having the Jar on the field does a number of things. Number one, it allows you to save any artifact from removal. But more importantly it lets your opponent know that you can save any artifact at any given time. Thus the "political" aspect. It controls your opponent in an unseen way because it does make them consider what they want to waste to get rid of the Jar. And as zyphermage said, that is definitely a little victory. Memnite really is only useful for Springleaf Drum or some early damage if there are no blockers, but mainly for Drum and to activate Metalcraft. Typically none of those things should be too difficult in Affinity, so I have been questioning Memnite's spot in my Affinity deck as well. I feel like I need the creature count, but in all honesty, he doesn't do jack mess, especially compared to what Welding Jar does.

@ CrovaxTheCursed I changed the line up of my deck to include Welding Jar over Memnite and Shrapnel Blast over Galvanic Blast. I am fairly confident that these are more streamline choices in the end. Do you have a link to any of those "political" articles? I'd like to read them. Thanks again for the feedback.

Unfortunately, I do not have any specific links. I occasionally surf around and find that stuff, but I forget to mark them. I have seen on this site though, a deck list that basically includes all the political cards in the game, complete with a pretty good breakdown of the definition. Ofc, I forgot to favorite that page too, so hopefully someone can help out in finding it. Anyway, I dig the new deck list, and it play tests way smoother and much more aggressive. I will have to play around with using Shrapnel Blast over Galvanic Blast as well.

I'm not sure you really want 4x shrapnel blast, you probably only want to see 1 to end the game. Are you going to be able to reliably cast 2 of them?

@ CrovaxTheCursed I use to do that to, then I got tired of kicking myself for losing good articles that I wanted to share with people, lol. I'm looking forward to putting the new list through the wringer, so to speak. I'll dig around and see if I can find those links, and I'll share them with you if I do.

@ zyphermage Between Glimmervoid x4, Mox Opal x4, and Springleaf Drum x3, I am fairly confident that I would be able to cast 2 Shrapnel Blasts in a single turn, and most definitely I would be able to cast 2 of them in a single game.

I'm not doubting whether you are able to cast it, but whether you need it. You might as well throw back in galvanic blast, and add lightning bolt for lethal at this point, and swap the lands for mountains.

I guess you want to burn to finish off an opponent but every burn card in your hand is 1 less artifact too. I did question whether you could reliably cast 2 I guess my mistake, but my main question was even needing to. Or think of my question this way, just cause a playset is 4, why throw in 4 shrapnel blast without even thinking about it, instead of using 3 and another artifact or even 2 blasts.

@ zyphermage Honestly, the 4 are for rotation to ensure that I can see them. I suppose I could do 3 and pick up another artifact, but for now, I'm going to playtest with the 4 and see how it plays. If I drop to 2 or 3, what would you recommend I add then?
