So, is this a series?
I'm liking the idea so far, but here's my thoughts:
Life Bloom/Lotus Bloom: Already loving the 'creature'-conjuring permanent, as if it was a Firefly Queen but in a different section than being on the field being exposed directly to creature control (see Otyughs, Thunderbolts, and Fire Shields). Also, the creatures that are produced have NO attack, so essentially, they can't get killed by a carapace shield or the like - not to mention, flowers shouldn't just attack. A Pulverizer, Steal, or Deflag would own this card hard though unless protected by a Protect/Enchant Artifact, so there's a decent amount of balance to this.
Harvest is intelligently thought out - after a certain point, you could have a FIELD of these cards, all having a ton of
or
, and thus 'harvest' them all to gain quanta and recover HP (however, the way it's worded made me temporarily confuse it for an HP 'buff', like a Shard of Divinity, unless you're referring to it this way).
The only problem I see with this card is that it might as well be applied to almost every other element for quanta gaining (except darkness due to devourers, and fire due to cremation, and light due to those rustlers/leaf dragons). Then again, I realize how abusive some of those other elements could combine with this (Time and endless hourglasses + sundials + other cards).
Also, see multiple Rain Blooms + massive harvest + Ice lance. What if this card was used in excess in a duo
/
deck? I could see a deck with feral bonds, these guys producing Rain Lotuses/Blooms, and them being sacrificed without doing any actual damage until they the player uses an Ice Lance. Maybe I'm over-analyzing this though with my limited capabilities.
The artwork is also pretty, but it could be a little more cartoonish - that could be changed later.
Oh... and you might want to change the names, "Life Bloom/Lotus Bloom" to "Life Blossom/Lotus Blossom" to prevent confusion for players who are going to think inevitably: "Oh hey! This card will give me MORE
quanta than the rustler/leaf dragons! Oh wait...
"
