Ok...best way I know to ask this question is just to give the specific example I have in mind...
If I have {kaalia of the vast} as my general, can I cheat {sigarda, host of herons} onto the field? Not exactly sure due to the fact that sigarda is green but I'm not using green mana to put her on the field
No you can't. You can't run cards that go against your commander colors
Thank you for the fast answer :) don't like the answer but still thanks lol
No problem :)
