I play Magic.
My favorite decks (I play casual) that I have at the moment are:
A red black deck I like to call Sacrifice Burn (graveyard returns, dying effects *like deal 2 damage to target creature or opponent*, forcing opponents to sac creatures, kill spells)
A green white deck based around both populate and cat tribal *it has a decent amount of life gain included*
A red green deck based around Aether Rift and Beast Tribal *it is pretty much all permanents*
A blue white deck based around tapping creatures and putting nasty enchantments on them to prevent any combat damage to me through creatures
A mono black deck centered around life gain and life loss (very typical mono black, using life for card draw)
My color preference in order from most liked to least liked:
Black
Green
White
Red
Blue
