Cards like Trailblazer's Boots (Unblockable unless your opponent is playing an all-basics mana base and if they are, good luck?) and Prowler's Helm (who plays Walls these days
1 of 1 is a bit weird to me, once it has been obtained (and revealed), all other sealed product should take a hit in value (no idea how this affects things in the sports market though, can someone shed some light?)
The effort of upgrading it isnt worth it and there arent any exceptional standalone cards included
The symbol for Double Masters doesnt really break away from this- I guess it gets across the double theme and has the sort of curvy points that other Masters sets have had, but otherwise it is just there
What would make these weaker Pokmon special is if they have abilities that make up for the lack of HP in relation to the prize cards they give up
And, that's not even looking at how great it is in +1/+1 counters decks
