I'm not sure if this idea has appeared before but after 200 rounds of battle with a mono-life deck, I thought it would make life more interesting (pun intended) by giving the element a fun permanent control.
Overgrowth|Overgrowth
cost:
probably should be in the range of 6-12 life quanta
effect:
Add Overgrowth to the top of the target pillar/pendulum stack.
Overgrowth itself generates no quantum.
At the end of the pillar/pendulum owner's turn, the card beneath Overgrowth has its element changed to life and move to the appropriate stack (i.e. quantum pillar->emerald pillar; fire pendulum->life pendulum). This process continues until
a) the owner is purified
b) a spell is inflicted on the owner (poisons/neurotoxin/fire bolt/ice bolt/lightning/holy light/luciferin/heal), though the Overgrowth & spell nullified each other
c) Overgrowth is removed by pulverizer/steal/earthquake/trident (think of Overgrowth as a kudzu vine that clings to the pillar/pendulum beneath it, so destroying the card beneath destroys Overgrowth, while stealing that card is essentially stealing 2 life pillars/pendulums)
d) the owner plays another pillar/pendulum on top of Overgrowth, changing Overgrowth into an ordinary pillar/pendulum in the stack (i.e. pillars of
with another
pillar -> pillars of
)
e) Overgowth is the last card in the stack, then at the end of the turn, Overgrowth itself becomes a life pillar/pendulum depending on what the target stack was
usages:
a) wreak havoc on opponent's quanta source by changing them to life pillars/pendulums...at least until opponent draws another card of the same name to put on top of Overgrowth; however, you may actually give opponent another pillar for free
b) make opponent waste a heal
c) protect self against malicious spells (only for people who utilize life pillars/pendulums)
d) permanent control that may otherwise count as a pillar (though it'd be a waste of lots of quanta)
e) convert excess pillars/pendulums of another element into life pillars/pendulums
