Yes it can attack twice
it starts with 0 attack point but for every card you hold in your hand it gains 1000 attack points
Because there are no official rules for the Egyptian God cards, the only reliable way to destroy "Slifer the Sky Dragon" would be to destroy it in battle with a monster with equal or greater attack. This can be accomplished by using "Honest" while attacking/ being attacked by "Slifer", discarding cards from your opponent's hand to lower its attack, and more.
it depends on how many cards u have in ur hand
You do the titan firestorm attack by sacrificing both the winged dragon of ra and slifer the sky dragon.

His attack is X000. He gets 1000 POINTS from the number of cards you have in your hand. :)

The attack=cards in your hand multiplyed by 1000. Spells, traps, and effects doesn't work.

if you sacrifice ra and slifer while obelisk is on the field obelisk wood have infinite attack and nothing can stop him
It depends. Slifer the Sky Dragon has the potential to be WAY better then than Obelisk, but if you have a low amount of cards in your hand, it can be quite weak. I would use Obelisk, because the attack and defence of that card won't change, Slifer's will.
Slifer's ATK and DEF is X000 where X is the number of cards in its controller's hand. So if you have five cards in hand, Slifer is 5000/5000. The non game-legal print has no effect text so doesn't explain this, but the game-legal version does.
Slifer's ATK and DEF depends on the number of cards in your hand x 1000. So if you have 4 cards in your hand his ATK and DEF will be 4000.
