Submission - Control of Financial Flows (trifle Sudden)

Probably too good: you get another master phase, your opponent doesn't. Maybe with a cost of 1 pool.

I agree, way too strong...

Way too strong? I wouldn't play that card since there's the restriction to canceling trifles only.

Name: Wash
[Third:U, LotN:PS, KoT:U]
Cardtype: Master
Master: out-of-turn. Trifle. Do not replace until your next untap phase.
Cancel a master card played by your predator or prey as it is played (no cost is paid). That Methuselah gains a master phase action (if the canceled card is an out-of-turn master, the master phase action is gained during that Methuselah's next master phase).
Artist: Jeremy McHugh

In general I do not like the card since it's slight variation of Wash. Aimed as silver bullet against abuse of Villein.

Oops, I missed the trifle part of the card. Yeah, in that case, this card is, to put it mildly, not very useful.

What's a "financial flow"? There may be a better translation for what you're thinking.
