Not what you said. You said speed (Blessing+Dive) and life gain (Miracle.) You never said they had to come from the same card. :p
Speed: graboid
Life gain: stone skin
Speed: gargoyle+eclipse
Life gain: vampires, drain life, liquid shadow, vampire dagger
Speed: mutations, chaos power
Life gain: antimatter
Speed: chargers, titans
Life gain: black hole
Speed: physalia
Life gain: purify
Of course some of these are worse than others, and some work only upped, but still every of these elements can make a pretty fast deck. Maybe slower than adrenaline+frogs, but comparable to adrenaline+frogs+heals+staves
Of course if we go beyond mono, some elements offer even more (
offers snovas for example,
+
can also be a fast deck with healing, flying vampire daggers also offer both, etc.)
But... I feel this whole discussion should be moved to another thread, since it's hijacking a thread that had mostly in-topic posts so far.
