It is a rare card rom DM-03, berserker race, quite a nice picture, and an attack power that can add up to match SuperNecroDragon Abzo-Dolba"s!
Use this card when you have build up your fortress of light creatures and when your opponent's most powerful card e.g.Billion-Degree Dragon is placed on the battlafield and will attack on the next turn, summon it and make the Billion run away like a little girl from it as Alek's attack power would most probably be higher.
This card is most effective if you are using a pure light deck, especially a Blocker deck as a blocker deck's job it to summon tons of blockers which will prevent your opponent's creatures from breaking your shields, Alek's power increases by 1000 for each o0ther light card you have in your battle zone so start building your great wall of light blockers and summon this creature to overwhelm your opponent. After you are done with defence, it's time to attack and by that time, Alek will be very high-powered and it can destroy your opponent's shields!
Of course, use it as a combo with your other light cards for power and once you are satisfied, use Diamond Cutter and finish your opponent off with your blockers and this card as well.
The only weakness to your combo are creatures that can't be blocked, but since you are using light blockers, you can destroy them at your next turn when they are tapped but the main problem will be:power cards like crystal lancer and phantasmal horoor gigazabal will be your arch enemy, but Alek can overpower them soon enough.
It powers up by 1000 power for every other light card you have in the battle zone, it is a blocker and it can attack players.
It's base attack power is 4000 only and depends a lot on your other light creatures. The cost is also quite high, it costs as much as a Hanusa, but by the time, it could be more powerful than a Hanusa.
There is only 1 variation of this card and it is from the Rampage of the Super Warriors(DM-03) expansion pack
The Overall rating for this card, I would give it a solid 7/10 for turing its enemies solid.
