I occasionally get emailed this question and although the answer seems blatantly obvious to me, I’ll try to thoroughly answer the question. I release a new version of MTG Forge usually once every month or two. I try to add a few cards and fix a few bugs in each version. A reader sent me 20 or so creatures (thanks!!) so I’ll add then to the next release. I fixed the drafting code, which is currently broken. The wrong picture was downloaded for Imperious Perfect. I actually fix a ton of bugs myself since I play MTG Forge so much. When I play MTG Forge it is called testing :)
I know randomly adding new cards might seem lazy (crazy), but you have to remember that this is only a hobby after all. I’m not sure of any freeware program that has regular updates. I add cards that are interesting to me. I was thinking about adding Chameleon Colossus but I can’t do protection yet, so I wasn’t sure was it worth the effort. Sometimes I get inspired so I’ll add a card like Serra Avatar. I also tend to add high value or popular cards. When Thoughseize was getting so much publicity, it was a simple card so I added it.
Like I have said many times before, MTG Forge can only handle relatively simple cards. No cards that generate mana like Dark Ritual. No land or creature can generate more than 1 mana. A few static and triggered abilities like Glorious Anthem and Reach of Branches. MTG Forge only has around 10 cards with static and triggered abilities. And abilities that trigger on upkeep if they don’t require a target like Juzam Djinn. Counters like +1/+1 are not implemented and no protection either.
MTG Forge 2.0 should allow me to program at least twice the number of cards. Cue the cheesy background music, “Twice the cards, four times the excitement.” Yes you did read that correctly, version 2.0 will be exponentially more fun, you may never buy cardboard again, lol.
