Well Mtg is a very fun game, there are 7 different mana in the game. Which are red (mountains), blue (islands), white (plains), black (swamps), green (forests), and artifacts. The 7th is snow because its a substance that acts different then all the other colours, and yet can be on top and around of all the other colours. I.e. A snow covered forest, or a snow covered island.
You can build your deck off of any colour(s) of your choosing. And there are infinite combos and ways to win. A white deck could try to out mass his opponents to kill him with an army of weaklings, while a blue deck could instead remove your opponents deck from the game.
And unlike Yu Gi Oh, A million 1/1's can kill a 2/2 instead of the 2/2 killing the million 1/1's. And only 2 of the 1/1's would die instead of the million, and the 2/2 will also die. So whats the logic in Yu Gi Oh about one 2/2 being able to take on a million 1/1's and win? A swarm of bees can kill a person even tho the person is stronger than one bee...
