I feel the need to say this again here.
IMO they are all very useful;
strong attack ability cost same as upped quint(pricey but useful)
best in
deck but u can set UGs out wait for the right moment then bam! WIN!
use the infection effect or vampire effect to your advantage or both
works good in life/death decks preferably use ability on skeleton have e-bond out, EM possible
Use to stall or strengthen. can also used with rage potion or with gravity shield
We All know causing our opponent to heal us is a great thing
the ability here can be a weapon or a tool
"mmm tasty quantums I feel better" enough said
"Wow, that was fast"
strong and works well mono light, light/life, light/life/air
strong plus the advantage of knowing your opponents hand and drawing a card
the ability to create any of the others in the right deck is very powerful
