Battle Card

Battle Cards are weapons used by people in the MegaMan Star Force series. They are similar to the Battle Chips from the MegaMan Battle Network series. They are categorized into Standard, Mega and Giga cards, and are used by swiping them through one's Transer, Star Carrier, or Hunter VG.

Battle Card selection
In-battle, the battle cards are drawn up in a 3x2 fashion. Normally, MegaMan can only select Battle Cards in the same column, or Battle Cards of the same name at a time. White Cards are exempt to this rule. MegaMan can only select cards in the same row only whilst in a suitable transformation (any Star Break in the first game, and any Zerker Tribe, or while using the Side Select Ability in the second), and he eventually gets to do this automatically from the start of the third game.

Best Combo
In the first and second games, whilst fighting an EX or SP boss, the player can construct a Best Combo, which is a series of cards that can deal a total of 300 damage or more. The Best Combo can then be converted into a Legend Card by Legendary Master Shin, which will freeze time, and use the cards in succession without any worry of flinching. Brother cards can also use that Brother's equipped Best Combo as well.

In the first game, the Best Combo is generated using only Standard cards, needing to deal a total of 300 damage or more in the space of a single turn. In the second, the Best Combo can be generated using Mega and Standard cards, on the condition that the opponent does not move in between the attacks.

Favourite Cards
These cards are selected from within your folder, and are treated as white cards regardless of their original colour. When a Brother card is used, you can start a roulette between the Favourite cards of the Brother in question, with the card eventually becoming one of the randomly-chosen cards.

The first game allowed you to select 6 favourites. The second allowed only 4, and the third game traded this system with a White card system, where the player can download a preset selection of 4 battle cards outside of his folder that will be treated as his Favourites. This can be changed by using Wave Stations in-game, and by inputting codes similar to Wave Command codes.

Regular Card and Program Advance
Shooting Star Rockman 3 discards the Best Combo system, replacing it with the Regular Card and Program Advance systems from the Battle Network series. A card in the folder can be selected as a Regular card - doing so will result in the card always appearing at the top-left corner of the opening draw.

Program Advances also make a return in the form of Galaxy Advances. Selecting three specific cards in the correct order will merge the cards into a single White Battle card which becomes the Program Advance card. There are also boss-related Program Advances called Giga Advance, and can be powered up similar to the SP Mega cards from the previous two games by beating the R-bosses in faster times.

Support System
This is also introduced in the third game. With the new design of the Custom Screen, several cards are positioned a bit off-centre, and Mega and Giga Cards take up more space on the screen. This results in some cards being covered by others(forcing you to pick them in a certain order), and they appear dimmed out, selectable only by touching them. Touching these cards allow you to either use their support function (this results in them being exempt from the normal card selection rules), or use the card itself. Doing the latter action makes you unable to select any other card for the turn. Dimmed out cards can be used normally once they are no longer covered by any other card.

Different cards have different support functions depending on their element. There are also Ability Waves that force the support cards to have a certain support function regardless of their element.
 * Elementless cards give Area Eater
 * Fire cards give Atk+10
 * Aqua cards give Invisible
 * Elec cards give Paralyze Plus
 * Wood cards give Grass Stage

X Cards
Similar to Dark Chips, X Cards are cards in StarForce 3 that, like their predecsors, are more powerful than their normal counterparts. However, the boosts aren't as big, and the player can insert as many as he wants in his folder, with no bugs occuring on use. These cards are extremely hard to obtain, but often appear when the Finalize Noise is activated.
