E Commit, ready 1 of your opponents foundations: Your opponents attack gets +2 speed. Draw 1 Card.

Am i correct in assuming that if i play this on my attack instead of my opponents i just get to draw a card (albiet rather expensively)?

yes.

It would not be the case however if it said "only playable on your attack"

*stamp*

I approve this answer.

ok, but

i n what phase or turn?

on my opp turn, or combat phase

if i play an attack in my turn, can i active that card?, i think not or yes?

during any enhance step

mm im so little confuse

if i play an attack in my turn, and i play Selflesss Giving enhance in my turn, how is posible give +2 speed to my opp's attack if they haven't an attack in play?

can active the effect and then draw a card

that effect may be followed? or they are 2 effect in one by the point as a separation?

if right, what happens with rejection vs yang** response?

(Rejection: Gain 3 vitality. Reduce this attack's damage to 1. if it is your turn, discard this card from your card pool.)

Yang**

R commit 1 foundation: after your opponent plays and ability that would reduce damage, cancel that ability's effects.

granting the opponent's attack +2 speed and drawing 1 card are two entirely separate events in the same ability. There's nothing in the ability connecting the two effects, they just both happen. One does not rely on the other.

So if it's during your own attack, you will just draw 1 card.
