WTQ...? It's so not a card...
100 damage with 100 damage to self on a failed flip is plain pwn-seek... The first attack can give your opponent a free turn if fails - it'll be at least usable if it still does the damage on a tails but no effect, so whether it's worth a try or not, it's up to you... (I say it's not...) Anyway, if there's still ex's, then do it on a basic ex with <100 HP (or stage 2 with C weakness) is not a bad idea - if you're lucky, you take 2 free prizes; if not, you still get 1 more than they do.
If the effects of the 2 attacks are swapped, i.e. first attack does 30 recoil on tails, second one fails on tails and gives you invulnerability on heads, then this thing is not that bad...
Weakness +30 is bad considering its HP is low, and free retreat doesn't help at all because if you fail the flip, it'll go down with the enemy anyway.
Conclusion - if you like pwnseek cards, use the red Gyarados or some other shiny; if you like suicide bombers, use basics and stage 1's instead. Using a stage 2 card like that is just not worth it...
