Manual mana sources activation

[zamprox84]

Hi everyone,
I was wondering if there is any possibility in the next Magarena releases to let the player tap lands (or any other mana producing permanent such as birds of paradise, llanowar elves, moxes, etc...) manually, even if no spell needs to be cast. Consider, for example, a situation like this: you have only a Quirion Ranger in play with an untapped forest. In your hand, you have only a 2 green mana spell you'd like to cast. You may want to tap the forest to get the first G mana, then use the Quirion Ranger ability to return the forest in your hand, cast it again, acquire the second G mana, finally cast the 2 GG mana spell.
Another example: you have 10 lands in play and want to cast Upheaval. You may want to acquire mana from all of your lands first, cast Upheaval, and play other spell using the mana just collected in your man pool.
This is unfortunately impossible at the moment because, even if you could cast the spell using the Ranger trick, the spell in your hand is not targeted as cast-able because of the nominal cost from the Magarena engine. Same for the Upheaval scenario.
Anyway, the game is great and I'll be always gratefull to all developers (I am a java developer myself) who made this real!

It is not too hard to allow the player to do this, the challenge is teaching the AI to tap for mana in this way as it requires planning several steps precisely. As a small step towards allowing more mana sources, we are currently considering cards that add multiple mana in https://github.com/magarena/magarena/issues/1528

Thanks a lot! I wasn't aware of the github issue, I guess that adding the capability of using multiple mana source (such as Ancient Tomb, City of Traitors, Black Lotus,Priest of Titania, Gaea's Cradle, Tolarian Academy etc..) should definitely be a great improve. I did had the suspect that teaching I.A. to use them is far way more challenging!
