Collectible Card Game Headquarters

Hello everyone, yesterday when playing magic the gathering i had a Stroke of Genius, but unfortunately to make this happen i need help with the following cards. First off: I have almost no experience creating cards but i do manage to create really awesome decks once in while. of course: after trial and error . The cards i request are so awesome in general that any deck could use it. And it would be amazing if someone can help me with them: I can make Basic Creatures and yeah thats it lol O.o Anyways these cards are hard for me to make i have no idea where to start so lets take a look:

Blight ?
Contaminated Ground X
Cursed Land ?
Evil Presence X
Funeral Charm ?
Entomb √
Sinkhole √


Other Cards:
Mire's Toll √
Hymn to Tourach √
Pestilence √
Entomb √
Choking Sands √
Sinkhole √
Wasteland √

You'll have to abandon the idea because granting a basic land sub-type isn't supported by the game. If you give the Swamp sub-type to a nonbasic land, it won't automatically produce black mana, and you can't grant it the ability to produce black mana because granting mana abilities from a card without mana abilities makes the game crash. Sure, you could give the basic supertype together with the Swamp sub-type, but this way not only the card would be partially wrong, but I also can't predict what would happen if a nonbasic land that already has a mana ability of its own (Valakut, the Molten Pinnacle for example) becomes basic with a basic land sub-type... chances are it would keep its old mana ability together with the new one.

thats a shame

But in the time that i made this post and replying i have made a working Entomb card. So i will mark that one for created. I will make this deck possible bit by bit!
