Anyway, let's review some more Yusei Cards. Let's start with Rockstone Warrior:
You take no Battle Damage from battles involving this card. When this attacking card is destroyed by battle and sent to the Graveyard, Special Summon 2 "Rockstone Tokens" (Rock-Type/EARTH/Level 1/ATK 0/DEF 0). These Tokens cannot be Tributed for a Tribute Summon.
Rockstone has two effects. The first effect is a Continuous Effect that prevents Battle Damage. The second is a Mandatory Trigger Effect that activates at the End of the Damage Step. Probably the most important thing to notice is that the first effect is applied if Rockstone attacks or is attacked, but the second effect requires Rockstone to attack a monster with equal or more attack. It doesn't work if it is attacked. As usual, remember that the tokens have no effects, and the restriction on being tributed is a Condition set on them.
The other Warrior I missed was Fortress Warrior:
You take no battle damage from battles involving this card. Once per turn, if this card would be destroyed by battle, it is not destroyed. (Damage calculation is applied normally.)
Both effects are Continuous. More notably, the second effect is applied automatically the first time Fortress Warrior would be destroyed in battle. You cannot choose not to apply it.
There are two more Warriors that don't fall into the Warrior theme. One is Zero Gardna:
You can Tribute this card to activate its effect. If you do, monsters you control cannot be destroyed by battle, and you take no Battle Damage, during this turn. This effect can be activated during either player's turn.
Gardna has an Optional Quick Effect. Tributing it is a cost. The effect can be activated during most part of the turn, but not during the Damage Step. The effect sets a Condition similar to that of Waboku. It will also protect monsters that are Summoned after the effect resolves. Note that you do not need to control any monsters in order to activate the effect.
The other remaining Warrior monster is Ghost Gardna:
When a face-up monster you control is selected as an attack target, you can change the target to this card. When this card is destroyed and sent to the Graveyard, 1 face-up monster your opponent controls loses 1000 ATK, until the End Phase.
This Gardna has two effects. The first is an Optional Trigger Effect. It is activated upon Attack Declaration, and it doesn't target Gardna itself or the opponent's monster. The second effect is a mandatory Trigger Effect that activates regardless of how, when or where Gardna is destroyed. This effect does target a monster.
Moving into weirder Cards, we have Level Eater:
If this card is in the Graveyard, you can activate its effect by selecting 1 face-up Level 5 or higher monster you control. Reduce that monster's Level by 1. Special Summon this card from the Graveyard. This card cannot be Tributed except for a Tribute Summon.
Level Eater's first effect is an Ignition Effect. It targets a high Level monster on your side of the Field. The Level is reduced as part of the effect. Note that there are no restrictions on how many times you can activate this effect, so you can activate it more than once per turn if Level Eater remains in the Graveyard. The second effect is a Continuous Effect, and it can be negated by Skill Drain.
Another random monster is Hanewata:
You can discard this card to make any effect damage you take this turn 0. This effect can be activated during either player's turn.
Hanewata has an Optional Quick Effect. Discarding it is a cost. Hanewata sets a Condition that reduces Effect Damage. You can chain it to an effect that inflicts Effect Damage, but it's not necessary.
Speaking of weird random Cards, we have Eccentric Boy:
When using this card as a Synchro Material Monster, the other Synchro Material Monsters is 1 monster in your hand. The Synchro Monster that used this card as a Synchro Material Monster cannot activate its effects, its effect(s) is negated, and is removed from play when removed from the field.
Eccentric Boy's strange set of rules are Conditions that cannot be negated. You must still fulfill any requirements that the Synchro Monster may have (such as a Spellcaster non-Tuner for Arcanite Magician), and you can only use 1 Non-Tuner monster, so you cannot Synchro Summon a monster like Mist Wurm. The effect prevention and negation only lasts while the Synchro Monster is face-up on the Field.
No Duelist is complete without a set of chickens. Yusei has two, and both have similar effects. One is Sonic Chick:
This card cannot be destroyed by battle with a monster that has 1900 or more ATK.
And Shield Wing:
Up to twice per turn, if this card would be destroyed by battle, it is not destroyed.
Both have Continuous Effects that prevent destruction in battle. The only note to add is that for Sonic Chick, the monster must have 1900 ATK at the Damage Calculation Sub-Step.
One more monster batch to go! If you have any questions, feel free to drop me an e-mail at ness00[at]gmail[dot]com.
