I was programing some support entiry cards and i realize i needed a draw card so this is what i have in mind
Normal Trap Card/Entity Fortune Gate
If you control 3 or less monsters, including at least 1 Spellcaster-Type monster you can activate this card from your hand. Draw 1 card for each monster type you control (Fusion, Synchro and Xyz).
I dont know how to even start with this card since theres no card in the game with a similar effect.
