Community Project - List of Repeated Card Concepts

[ZephyrPhantom]

Okay, we've had multiple attempts at this thread including this (http://elementscommunity.org/forum/index.php/topic,35608.0.html) and this (http://elementscommunity.org/forum/index.php/topic,36204.0.html), but after a bit of discussion between some card designers and our Idea Guru OldTrees, we're starting fresh.

Objective of this thread : To collect commonly repeated Card Concepts. Concepts can be both related to theme and ability, but in general should be a topic that has been attributed to many times before within CI&A within some form.

Unlike the previous threads, I won't be including any grade system of sorts or actual delinked card images, just links to the card ideas that the concept has appeared in. Any card concept that gets posted on this thread requires at least one (preferrably two) threads linking to previous use of the concept. If a card concept has at least 4-5 threads being linked under it in this list, then chances are you'll probably want to try something else.  If you wish to attempt an idea using one of these concepts again, be sure to provide reasonable justification for why you are reposting this concept but do expect a reduced chance of this card getting into the Crucible unless you're ready to defend the idea's uniqueness.

That being said, on to the list:

Moving a Creature into another slot to explicitly work with Flooding
(Note :This idea is rather common as a spell. A creature or permanent might be possible if "move creature just to synergize" with Flooding is not the only focus of the card.)

You're always welcome to try to use ideas with this concept but if you do, keep in mind that several cards with the same intent have been posted already here.

Feel free to suggest any concepts you feel are commonly used within the community and remember to provide at least 1 link to such a topic along with a good reason you feel this concept is redundant. Let the suggestions come in!

Zombies are common, i think

cards which reposition your opponents creatures (so that you can kill them with flooding).  it has been suggested many times before, but the most recent is
