Zekrom is a powerful pokemon with no apparent weakness, a great choice for your deck.
I have 2 uses that are effective.
1: Use as your first pokemon to get rid of 3 or 4 of your enemy's pokemon.
2: Use as your last Pokemon to win the game.
Strategies and game play:
The best play for me is to get a lot of electric pokemon and load up on electric energy and just reak hit points.
Combos with other cards:
Pair with a Zapdos or a Ampharos because they are both good pokemon that will pretty much win the battle.
Ways to counteract it:
Use a Landorus because it is counter active to electric attacks and doesn't take a lot of energy
1: it's very powerful
2: a lot of hit points
3: attacks do amazing damage.
1: Weakness is x2 on fighting types.
2: retreat cost is high (i would not retreat this pokemon)
3:It uses a lot of energy.
4: your enemy takes 2 prize cards when its knocked out.
foils: I may have one (not for trade) but there out there.
Language: i have an english one and i am almost positive there is Japanese too.
Artwork and aesthetics:
I like the art because it just pops out and looks fierce. The art does go with the cards powers.
10 (i wish there was more because it is a great card).
