You can discard Machine-Type monster(s) whose total Levels equal 8 or more to Special Summon this card from your
hand or Graveyard. When this card is destroyed by battle and sent to the Graveyard, select and destroy 1 card your
opponent controls. When this face-up card you control is targeted by an opponent's Effect Monster's effect, look at your
opponent's hand and discard 1 card from their hand.
You can Normal Summon this monster.
Special Summoning this monster with its effect does not start a Chain, similar to Special Summoning Cyber Dragon.
You can negate this Summon with
"Thunder King Rai-Oh" or
"Solemn Judgment."
The effect that destroys 1 of your opponent’s cards targets that card.
You can discard
"Machina Fortress" itself as part of the cost to Special Summon it.
Discarding Machine-Type monsters is a cost to Special Summon this card.
Your opponent will miss the timing to activate the effect of
"Archfiend of Gilfer" if it is discarded by the effect of
"Machina
Fortress."
If your opponent targets
"Machina Fortress" with an Effect Monster’s effect, then Chains with
"Enemy Controller" to take
control of
"Machina Fortress," you will not discard a card from your opponent’s hand because it is no longer being targeted
by an opponent’s effect.
If you have more than 1
"Machina Fortress" on the field and your opponent targets them all, you will discard 1 card from
your opponent’s hand for each
"Machina Fortress" targeted.
When this card is targeted by an opponent’s Effect Monster’s effect, you look at the opponent’s hand and discard 1 card
from it immediately before resolving the effect of the Effect Monster. For example, if
"Machina Fortress" is targeted by
your opponent’s
"Brionac, Dragon of the Ice Barrier" you first decide whether or not you want to Chain any effects. Then,
when you go to resolve the effect of Brionac, first look at your opponent’s hand and discard 1 card from it. Finally, resolve
Brionac’s effect and return
"Machina Fortress" to your hand.
If
"Macro Cosmos" is active you won’t be able to discard
"Machina Fortress" as part of the cost to Special Summon the
same
"Machina Fortress" because it will be removed from play.
