Lastly we have Reyhan who essentially gives all your creatures modular. The Corpsejack Menace is always a doubling of the counters which can get out of hand with a couple of cards but for the most part it is just a bigger, costlier version of the Constrictor. The Constrictor and the Scales are nice cheap things that increase the number of counters by one, which in most cases is double. The main engine cards for this deck are the things that increase the +1/+1 counters added to things. The importance of Walking Ballista is why I am running the Den Protector but something to find it from the library is probably worth finding space for. Looking mostly at that Servant! Due to the high power of a couple of specific interactions it feels like some creature tutor effects may well be a nice way to power this list up. Some of the deeper cards may also turn out to just not be worth it. I expect I will want to replace them with some more removal. I expect some of the higher power cards that are off theme somewhat like Kalitas or even Scavenging Ooze may well be easier to cut after testing. That way I get to see which cards are weaker and what I need more of. I went super light on group four cards so as to maximize the synergy cards for a first run sort of deck. Mixing that lot together I got this list. Some one mana ramp is likely well worth some space In our last group we have loads of options too but far less space In our third group we have the bulk of the cards (arguably some of these should be in group 2) The deck wants four kinds of cards, things that improve +1/+1 counters, things that are improved with +1/+1 counters, things that give or gain +1/+1 counters and then some interaction, removal and disruption. The problem is that you leave very little space for solid interactive cards which you will need to not fold to certain cards you might face. The more synergy you ram in the better that aspect of the deck gets, each card with +1/+1 counter synergy improves. The issue for this deck will not be lack of cards but rather lack of space. The last couple of sets haven't offered all that much to power this kind of thing even more but we already have plenty. Then again, when Winding Constrictor came out it looked even more appealing.

I first wanted to do this when Reyhan was released but never got round to it. I don't expect this to be tier one by any means but it has a lot of depth in support and even in payoff while containing a lot of independently powerful cards.
