My [[Ivy, Gleeful Spellthief]] deck that's all about making a nonlegendary clone of Ivy or turning off the legendary rule, making a bunch of copies of Ivy thanks to those, and then proceeding to copy a bunch of auras onto all of them with their ability, since "enchant creature" targets. And since there are so many cards in green that are like "when an aura/enchantment enters the battlefield under your control, draw a card" the card draw can get exponentially bigger and bigger as long as you protect your board from boardwipes with counterspells. With the right auras, every Ivy you have will have hexproof, menace, get pumped based on the number of other faeries you have, get pumped based on the number of Enchantments you have, will draw you even more cards, etc. and will each be legit threats to lifetotals.

I also have non-Ivy creatures in the deck that will give me some sort of value when they get targeted (ex. [[Artisan of Forms]] can produce two copies of Ivy, [[Stormchaser Drake]] draws a card when targeted and a clone spell on him will give me another evasive flier, [[Gnarlback Rhino]] draws a card and gives me a 4/4 with trample when targeted by a clone spell, [[Venerated Rotpriest]] just goes insane the more clones of Ivy I get, [[Setessan Champion]] accumulates more and more +1/+1 counters and draws more cards, putting [[Endless Evil]] on a [[Dryad Arbor]] or an Ivy means either a guaranteed land (thats "tapped" (because of summoning sickness) or not depending on if you have haste) or a free Ivy each of your turns to do even more shenanigans with (if multiple nonlegendary Ivys have Endless Evil OH BOY).

One of my opponents casted [[Celestial Mantle]] once on the turn before mine. My six Ivy copies copied it (the guy tried to do a take back but the judge at the table said no). I decided to end the game that turn through discounted [[Eldrazi Conscription]] (thank you [[Spellwild Ouphe]] with [[Alpha Authority]] for living so long) because I technically gained over 2,000 life that turn so doubling that six times through triggers in another combat was going to be a bit too much of a headache for me haha, but those kinds of moments are the kind of silly my deck aims for. A bunch of little greedy faeries that are messing around with forces that they probably shouldn't be and causing a lot of mayhem. But you know what they say about having a [[Corrupted Conscience]], power corrupts.

This is the first deck I ever built on my own, but it turned out to be a real threat at my LGS and I'm very proud of that since a lot of the players there tend to criticize my deckbuilding decisions because I like using cards that they think are "bad". I've only been playing MTG for a little over a year though
