Good points!
- Tsabo was added when the deck was much more focused on lands and it doesn’t really fit anymore.
- Bola’s Citadel is a bad excuse for being able to play the top card (aka draw replacement). I will replace it. I am always quite low with my landbase, but no reason to keep that bad habit up
- Keen Duelist looks like such a fun card. I am not sure about the higher cmc draw cards you suggested, but the lower ones
- I feel like the Necromancer’s are awesome because they do not cost that much and my commander allows me to recast them. Getting any creature temporary for 3 or permanent for 4 is just insane. Invader Parasite is the one card that is a bit more aggressive on land destruction as it hits general lands. I kinda still want to include it, because nuking a forest really makes recovering with land ramp very difficult - I know it is a bit off theme. Instead of removing dread return, I removed beacon of unrest. I feel like the 1 mana less really can be beneficial and casting form the graveyard for sac 3 while costly is sometimes playable - especially when sacrificing copies that only last till end of turn.
- I always feel like Final Parting is a bit slow, but at the same time: yea the value is insane. Coiling Rebirth could replace dread return… alright let’s try that.
- I also added buried alive for goblin ruinblaster, but I don’t feel very good about that one given that this thins my nonbasic hate - however, it also enables getting the good haters out
Yes, it is absolutely valid that you decided to commercialise your project and keeping parts or all of the code closed. As I work in the public sector and we are encouraged to use open source and write open source software, my knowledge regarding closed software solutions is thin. Is there a “standard way” how closed software is able to guarantee private key safety? I could imagine solutions where there is a separate handler that is open source so that one can verify that only specific information is passed into the closed software area, but this doesn’t sound feasible when talking about full terminal support within the closed software.
Again, there is nothing wrong with going commercial! I am sure I will release closed software (side projects), too, at some point.
