If Pokemon Tower Defense is like the real Pokemon games with the evolution system then you will not be able to evolve Graveler by leveling, you will need to trade with someone (If you are able to trade)
yes you can
Ill trade you if you have any shiny or shadow

Haunter Evolves by Trade.
trade while holding a kings rock
The shiny rattatta code for Pokemon tower defense is 01543on4
you create a trade and you go to one of your other profiles and you put your pokemon in the trading center and go back to the other profile and you accept the trade.
You can already trade Pokemon with other people from PTD. You get codes that you give to people and vice versa which will end up helping you get higher leveled, better Pokemon.
Graveler doesn't evolve by level, you have to trade back & forth
No, Pokemon Tower Defense includes only the original 151 Pokemon cant get Arceus on Pokemon Tower Defense cause Sam didn't added it on the game but u can get some others like Raikou , Entei , Suicune , Victini (only on Pokemon Center).
