Excellent 3-Type Deck, and Why - Destroyer

Hey everyone. Here's my layout for a pretty good 3-type deck. It uses 
Darkness for some high attack blockers, as well as excellent spells. It also

uses Nature for fast mana, decent attackers, and retrieving monsters. Last 
but not least: Water, for low-cost blockers, as well as some higher attack 
blockers in addition to Creature "Bounce" cards. I try to keep the blockers 
to a low-cost so they can be brought out fairly quick, and added in some 
decent power monsters for back-up when they need it. It doesn't have much of

a problem since most of the monsters are low-cost and you only need at least

1 mana from the civilization of the monster you're summoning. The spells 
from the Darkness civilization are mainly used later in the game or not at 
all (because I used them for mana). What's nice is that some cards like Dark

Reversal, Ghost Touch, Dimension Gate, and Spiral Gate are all shield 
triggers, and deadly one's at that. Nine shield triggers means I have less 
than a 1 in 4 chance of one of my shields being one of those cards. Not the 
greatest of odds, but every little bit helps.
