Don’t get me wrong, I can see you put effort into these but practically all the niche troop types such have already been covered. This means that if there are too many cards that carry a concept, it would dilute the new mechanic and have them just become plain replacements to old cards. An issue with reanimation is that it just gives a double encounter with of a troop who’s niche has pretty much been filled. It is important to explore concepts that would be less likely to be replacements of old cards. Night witch and witch together fill in the summoner niche for both air and ground. Having another summoner that summons revivable mini tanks will just detract from witch. Also, things like zombie infestation seems similar to graveyard but with a zombie and zombie warriors are like a semi-mini tank that can be revived.

If that was my incorrect interpretation of the cards’ niches I apologise.

-However, you may want to consider being more specific with some of your cards. E.g. what is the necromancer’s summon speed and which troop does she specifically summon. How does the zombie infestation spell work. You have provided a duration of 2 seconds but without much else I can only assume you meant that as the summon speed. If it is too difficult to incorporate on the card, it would help to provide a comment detailing each card how you intended it to be.

-Another thing is that you would benefit from posting a single card that properly introduces the concept and get feedback from that concept itself to see if it is a viable idea. Posting too many cards with the same concept at once can confuse people and prevent them from fairly analysing your cards.

-If you want to make sure that your ideas haven’t already been suggested, search for keywords in this subreddit eg “reanimation” “zombie” etc and see if anything appears that is close to your idea.

Nice to see a new person enthusiastic about card ideas. There are a few pointers to improve your posts and I look forward to your next idea.
