-ARMED AND 
DANGEROUS
these are what i think are the top 5 
shield triggers:
5.TORNADO FLAME:its a pretty basic 
monster removal spell and can be pretty reliable in tight 
spots.
4.SPIRAL GATE:like tornado flame it 
can be very helpful in a tight spot.could get rid of a big creature just in time 
to attack.
3.NATURAL SNARE:this used to be one 
of my favorites and can also get rid one pesky creature that gets in your 
way.
2.TERROR PIT:unlike natural snare it 
sends the creature to the graveyard without giving your opponet extra 
mana.
1.HOLY AWE:yep the one and only holy 
awe.this card has got me out of alot of tight 
spots.
