If a card requires a 2+ combo to be useful and if that combo only has 1 option for the other card then the card it far far too situational.
A 2|6 for 5
is a really, really poor fighter. Therefore, the only point of Tempest Flyer is using it's ability. Since the only point of using the ability is to kill with flooding, this card is useless without flooding (what, get an EM by pushing an antimattered creature back? that's even more situational) and OP with flooding (insta-kill on a stick for 1
is OP).
I suggest raising its attack to 4 in both version, and offset by increasing the skill cost to 3|2. This way it is much less situational, and less OP when combined to flooding.
