Well it seems to me that we've gotten just about all the posts that we are gonna get so judging time.

Burn The Witch
Trap Card
Tribute 1 Pyro type monster or fire attribute monster to destroy all spellcaster type monsters and spell cards on the opponents side of the field and in there hand. Then for a number of turns equal to the level of the tributed monster your opponent must show you any cards they draw or add to there hand if it is a spellcaster type monster or a spell card it is sent to the graveyard every time a card is sent to the graveyard by this cards effect do 200 points of damge to the opponents life points.
creativity 6/10 (Good concept I like the idea of burning like in the old witch hunts, but its CCV for pyros)
hate 7/10 (Make a comeback on the part of the spellcaster player pretty much zero, but it hurts any deck because it also hits spell cards)
wording 3/5 (missing capitals, misspellings)
elegance 4/5 (a bit wordy, but not bad)
The Age Of Science
Field Spell
All Spellcaster type monster effects are negated.
When ever a spell or trap card is played you can disard 1 card from your hand to nagete the activation and effect of that card. If you discard a physic or a machine type monster for this cards effect you can draw 1 card from your deck.
creativity 8/10 (skill drain + royal oppression why is this a field spell exactly?)
hate4/10 (stopping all their effects is good, but the second effect is useful against any deck.)
wording3/5 (again spell check is your friend)
elegance5/5 (fine)
Spell Pressure
Continuous Trap Card
You can only activate this card as Chain Link 1. While this card is face-up on the field, both players must discard 1 Spell Card when they Summon a Spellcaster-Type monster from their hand. Neither player can Summon Spellcaster-Type monsters from the Graveyard.
creativity 9/10 (Not groundbreaking, but certainly unlike anything I can think of)
hate8/10 (Not many ways around this one, and will pose a major roadblock against spellcasters)
wording5/5 (You’ve done this before)
elegance5/5
Bad Reaction to Magic
Effect Monster (Spellcaster / DARK / / ATK 200 / DEF 600)
FLIP: Put 1 Spell Counter on each face-up Spellcaster-Type monster on the field. When this card is removed from the field, destroy all monsters on the field with a Spell Counter(s) on them, and each player takes 200 damage for each Spell Counter removed from their side of the field.
creativity 8/10 (I love the reference to the other bad reaction card, I’m not sure if it could work though. I think you can only put spell counters on cards whose effects allow it.)
hate7/10 (you can ram it into another monster to inflict massive damage, and there is no way around it really other than using up all your counters)
wording5/5 (again spell check is your friend)
elegance5/5 (fine)
So I guess Maruno has it
