I have no idea what i'm doing

Conspiring Regent
(B)(2)
Creature - Human
T: Add 1 (B) mana to your mana pool.
Power is wasted on the monarchy.
[ 1 / 1 ]

Sunder
(B)(B)(U)(2)
Sorcery
Scry 3. For each card you put on the bottom of your deck, pay 3 life and destroy target creature.
Let the axe fall where it may...

Cascading Floods
(B)(B)(B)
Instant
Counter target spell, if a spell is countered this way you may copy that spell (choose new targets for the spell)

Venusian Scrambler
(W)(W)
Creature - Venusian Warrior
T: Target creature is unblockable until end of turn.
Feeding off brain pulses, Venusians find the raw emotional nature of humans quite tasty.
[ 1 / 2 ]

The proper syntax for the colors is

W-white
U-blue
B-black
R-red
G-Green

Some wording suggestions

Cascading floods
Counter target spell,if a spell is countered this way you may copy that spell, choose new targets for the spell

Vesuvian Scrambler
T:Target creature is unblockable until end of turn

Sunder is ridiculously powerful and kind of breaks the color pie.

Yay, now i have some idea of what i'm doing!

I made some edits, is good now ja?
